Two of the more common household products containing sodium hydroxide are drain cleaners and oven cleaners. When most pipes are clogged it is with a combination of fats and grease. Cleaners that contain sodium hydroxide (either as a solid or already dissolved in water) convert the fats to soap, which dissolves in water. In addition, when sodium hydroxide dissolves in water a great deal of heat is given off. This heat helps to melt the clog. Sodium hydroxide is very damaging to human tissue (especially eyes). If a large amount of solid drain cleaner is added to a clogged drain, the heat produced can actually boil the water, leading to a splash in the eyes of a solution caustic enough to cause blindness. Some drain cleaners also contain small pieces of aluminum metal. Aluminum reacts with sodium hydroxide in water to produce hydrogen gas. The bubbles of hydrogen gas help to agitate the mixture, helping to dislodge the clog.. Oven cleaners work by converting built up grease (fats and oils) into ...

Sodium hydroxide is a popular strong base used in industry. Around 56% of sodium hydroxide produced is used by industry, 25% of which is used in the paper industry. Sodium hydroxide is also used in the manufacture of sodium salts and detergents, pH regulation, and organic synthesis. It is used in the Bayer process of aluminium production.[15] In bulk, it is most often handled as an aqueous solution,[29] since solutions are cheaper and easier to handle. Sodium hydroxide is used in many scenarios where it is desirable to increase the alkalinity of a mixture, or to neutralize acids. For example, in the petroleum industry, sodium hydroxide is used as an additive in drilling mud to increase alkalinity in bentonite mud systems, to increase the mud viscosity, and to neutralize any acid gas (such as hydrogen sulfide and carbon dioxide) which may be encountered in the geological formation as drilling progresses. Another use is in Salt spray testing where pH needs to be regulated. Sodium hydroxide is used ...

Previously, sodium hydroxide has been prepared using two processes namely, an Electrolytic process and Caustisization of soda ash. Both methods require a lot of energy and products made under these conditions are very expensive. The present study was aimed at investigating whether barium hydroxide rather than slaked lime can be used in the lime-soda process. The barium hydroxide was obtained from carefully selected barium compounds which thermally decomposed within temperature ranges of 600°C-700°C to barium oxide. The barium compounds used were barium sulphite and barium nitrate. The barium hydroxide was reacted with sodium carbonate and formed sodium hydroxide and barium carbonate as slaked lime in the lime-soda process that produces sodium hydroxide and calcium carbonate. The results have confirmed beyond any reasonable doubt that both barium sulphite and barium nitrate readily decompose thermally in the temperature ranges 650°C-700°C. Barium sulphite decomposes to barium oxide and ...

Sodium hydroxide is an alkali which is also known as caustic soda. Caustic means "burning" and caustic soda takes its name from the way it can burn the skin. It has the chemical formula of NaOH. It is a base, meaning it has a high pH. It is the most common thing used to raise the pH of solutions; for example, to neutralize an acid. As a solid, the alkali is deliquescent and readily absorbs moisture and carbon dioxide from the air. It dissolves easily in water, and makes the water warm when this happens. Sodium hydroxide is used as a solution called lye to make soap. Lye is also used to unclog drains. Its dissolving properties and its ability to easily break surface tension are fundamental for its uses. It works in two ways. First, it combines with grease to make soap. Second, it dissolves hair (which is soluble in any basic solution). ...

It is generally prepared by adding moderate amount of sodium hydroxide solution to a zinc salt solution such as zinc chloride or zinc sulfate. These two compounds react under normal conditions to form a white precipitate of Zn (OH)2. Dilute solution of sodium hydroxide should be used in this reaction in order to prevent the inorganic compound from dissolving. Under normal conditions, the zinc salt dissociates to form a zinc ion that associates with two hydroxide ions from sodium hydroxide solution to form zinc hydroxide.. Zn2++ 2OH- → Zn(OH)2. If excess sodium hydroxide is added to the salt solution, the precipitate of Zn (OH)2 that is formed initially will dissolve to form a form a colorless solution of zincate ion as seen below:. Zn (OH)2 + 2OH- → Zn(OH)42-. This property of zinc hydroxide is extensively used to detect the presence of zinc ions in solution. However, it is not a unique method for testing as there many compounds of aluminum and lead that behave in a very similar ...

Introduction. ACID - BASE TITRATION AIM The aim is to perform an experiment involving the titration of an acid and base to find the end-point of the titration in order to determine the molarity of the sulphuric acid. GENERAL BACKGROUND According to Bronsted and Lowry (1923) an acid is defined as a proton (H+) donor, and a base as a proton (H+) acceptor. For example, sulphuric acid, a strong acid, is a good proton donor while sodium hydroxide, a strong alkali (soluble base) contains the hydroxide ion (OH-) which is a strong proton acceptor. The alkali which produces this OH- ion will neutralize acids by the reaction: H+(aq) + OH-(aq) --, H2O(l) This reaction is common to all neutralization reactions between acids and alkalis in aqueous solution. It should be noted that in aqueous solutions the H+ ions exist in their hydrated forms H+(aq). The most accurate method of measurement is to run the acid into the alkali from a burette. This is known as neutralization by titration. Titration is a ...

Subsequently, water is removed using an evaporator at a temperature of 40 to 50° C. The white residue is added to methanol using a beaker while being stirred at room temperature (about 10 to 30° C.), and then be stirred for 30 minutes. The resultant is dissolved and salicylaldehyde having the same number of moles as D,L-serine is directly added to this solution at room temperature (about 10 to 30° C.) while being stirred. At this time, the solution rapidly becomes a yellow color. Methanol is completely removed by an evaporator at the temperature of 30 to 40° C., the remaining yellow solid is dissolved in methanol in a beaker at room temperature ... CEDAR RAPIDS (KWWL) -- The Cedar Rapids Fire Department says Wright Brothers Boulevard is back open following a tanker rollover that caused a chemical leak.. A semi-tanker carrying more than 50,000 pounds of sodium hydroxide overturned while exiting I-380 onto Wright Brothers Boulevard Wednesday morning.. Police say the driver of the tanker, 39-year old Joe Short of Illinois, was turning left onto Wright Brothers Boulevard from the northbound I-380 ramp when the chemical inside the tanker shifted causing the trailer and the truck to turn on its side.. Short was taken to Mercy Medical Center with non-life threatening injuries. He was ticketed for Failure to Maintain Control.. A small drip of sodium hydroxide from the truck forced crews to established a 150 foot safe zone around the tanker while they cut a hole in the steel tank to create a relief valve in order to off-load the chemical. The truck was transporting the sodium hydroxide from Muscatine to Red Star Yeast in Cedar Rapids.. Sodium ... Method: Grind sample to pass 1 mm screen taking care not to overheat. Take approximately 1 g of the sample and add 25 ml of pure acetone. Stir for a few minutes, filter, and divide filtrate into two.

A uniaxial natural fabric of Hildegardia populifolia was treated with 5% sodium hydroxide solution for 1 h, and the resulting changes were analyzed by polarized and scanning electron microscopic techniques. The untreated and treated H. populifolia fabric was reinforced in epoxy and toughened with 10% polycarbonate. The variation of the flexural strength and flexural modulus with different fabric contents and fiber orienrations was studied. The effect of sodium hydroxide and a silane coupling agent on the flexural properties of the composite was also studied. It was observed that the flexural properties increased on alkali treatment and when the coupling agent was used. The morphology of the cryogenically fractured surfaces indicated good bonding between the matrix and the reinforcement when a coupling agent was used. © 2006 Wiley Periodicals, Inc.

Note what the question actually asks you, "roughly". Approximation is an important tool in ionic equilibrium calculations.. Here, you have$0.0126M \text{ }\ce{Ca}^{+2}$and$0.0252M\text{ } \ce{OH-}$in the original solution. By addition of$0.1M \text{ }\ce{NaOH}$, which is a strong electrolyte, youll not only add$0.1M\text{ } \ce{OH-}$to the solution, but also cause$Q$to exceed$K_{sp}$, hence, the salt will be precipitated out.. Now, the concentration of our ions before precipitation is$0.0126M \text{ }\ce{Ca}^{+2}$and$0.1252M\text{ } \ce{OH-}$. Let$y$be the fraction of existing ions that are not precipated out. So, well be left with$0.0126 \cdot y M \text{ }\ce{Ca}^{+2}$and$0.1252 \cdot (2y-1) M\text{ } \ce{OH-}$ions. Equating their ionic product to the salts$K_{sp}$, we get:. $$0.0126 \cdot y\cdot(0.1252\cdot (2y-1))^2=8\times10^{-6}$$. $$y\cdot(2y-1)^2\approx0.0405$$ $$y\cdot(1+4y^2-4y)\approx0.0405$$.

The centimeter is a unit measure of length. The gram is a unit measure of weight. So, pH is the unit measure we use to say how much acid is in a substance. The pH scale goes from 0 to 14. A pH of 0 means a very high acid activity. Substances such as lemon juice and vinegar are acidic with pH values of 2 to 3. Nitric acid and hydrochloric acid are very strong with pH values of 0, while stomach acid has a pH of 1. Addition of a strong acid, such as sulfuric acid ( H2SO4 ) to water makes the resulting solution very high in active acid concentration. This is called an acidic solution.. On the other end of the scale are the alkaline substances, which range from 8 to 14. Common alkalis are seawater (pH 8), household ammonia (pH 11), oven cleaners (pH 13), and the very strong alkali, sodium hydroxide (pH 14). The addition of a strong base or alkali material, such as sodium hydroxide ( NaOH ), to water makes the resulting ... 10. An alkyl halide when reacts with Aq.

Upon reacting with sodium hydroxide, both the Cu2+ and the Fe3+ cations would precipitate out of the solution. Copper (II) hydroxide, tlue he product of the cupric ion forms a light turquoise precipitate while iron (III) hydroxide forms a darker rusty red precipitate. Because the precipitate observed in the situation is of the darker variety, one might begin to suspect that the Fe3+ cation was present in the original solution and can rule out the presence of the turquoise copper precipitate. The Zn2+ ion would also react with the sodium hydroxide and would too precipitate out of the solution. However zinc (II) hydroxide is white in its precipitating form. Because of the fully dark color of the precipitate in the situation without any white particles standing out, one might begin to think that the Zn2+ ion is not, in fact, present. The suspicion of ferrics presence is further validated when sulfuric acid is added and the precipitate previously formed disappears. This makes sense with the ferric ...
