  • Standard reduction potentials for reactions directly involving nitrous acid are shown in the table below: The data can be extended to include products in lower oxidation states. (wikipedia.org)
  • molecule
  • Because transmembrane equilibrium must be maintained, another unionized molecule must diffuse into the cell to repeat the process. (wikipedia.org)
  • pKa ≈ 3.3 at 18 °C Nitrous acid is also highly volatile - in the gas phase it exists predominantly as a trans-planar molecule. (wikipedia.org)
  • alkaline
  • It forms the largest alkaline buffer in our blood and ensures that our blood remains slightly alkaline (= basic) (pH 7.365) by neutralizing acid waste. (alkavitae.dk)
  • Alkaline minerals are removed from the bones, teeth, nails, skin, hair and suchlike to bind with excess acids. (alkavitae.dk)
  • This is why weak acids are better absorbed from the stomach and weak bases from intestine where the pH is alkaline. (wikipedia.org)
  • Examples of bases are the hydroxides of the alkali metals and alkaline earth metals (NaOH, Ca(OH)2, etc. (wikipedia.org)

  • Choline, inositol and ascorbic acid are required in appreciable quantities in the diet and sometimes are not referred to as vitamins but as major dietary nutrients. (fao.org)
  • excess acid
  • By Le Chȃtelier's Principle, the release of CO2 from the lungs pushes the reaction above to the left, causing carbonic anhydrase to form CO2 until all excess acid is removed. (wikipedia.org)
  • Lewis
  • Lewis considered this as a generalization of the Brønsted definition, so that an acid is a chemical species that accepts electron pairs either directly or by releasing protons (H+) into the solution, which then accept electron pairs. (wikipedia.org)
  • ammonium

  • Ammonia
  • Ammonia and other bases similar to it usually have the ability to form a bond with a proton due to the unshared pair of electrons that they possess. (wikipedia.org)
  • An example is boron trifluoride (BF3), whose boron atom has a vacant orbital which can form a covalent bond by sharing a lone pair of electrons on an atom in a base, for example the nitrogen atom in ammonia (NH3). (wikipedia.org)
  • NaCl
  • Historically, this reaction was represented as acid + base(alkali) → salt + water For example: HCl + NaOH → NaCl + H2O The statement is still valid as long as it is understood that in an aqueous solution the substances involved are subject to dissociation, which changes the substances ionization state. (wikipedia.org)
  • stomach
  • Similarly, ingesting sodium bicarbonate with amphetamine, a weak base, causes better absorption of amphetamine (in stomach) and its lesser excretion (in urine), thus prolonging its actions. (wikipedia.org)
