The strength of the bonds between the metal ion and water molecules in the primary solvation shell increases with the electrical charge, z, on the metal ion and decreases as its ionic radius, r, increases. (wikipedia.org)
The aqua ion is associated, through hydrogen bonding with other water molecules in a secondary solvation shell. (wikipedia.org)
With the higher oxidation states the simple aqua ions dissociate losing hydrogen ions to yield complexes that contain both water molecules and hydroxide or oxide ions, such as the vanadium(IV) species [VO(H2O)5]2+. (wikipedia.org)
In aqueous solution the water molecules directly attached to the metal ion are said to belong to the first coordination sphere, also known as the first, or primary, solvation shell. (wikipedia.org)
With tripositive ions the high charge on the cation polarizes the water molecules in the first solvation shell to such an extent that they form strong enough hydrogen bonds with molecules in the second shell to form a more stable entity. (wikipedia.org)

These changes are related to variations in photosynthesis, calcium, dissolved oxygen, carbon dioxide, and redox levels that naturally occur in the aquarium. (seahorse.com)
In a healthy aquarium, the growth and multiplication of corals, calcareous algae and other organisms can result in calcium depletion. (aquasd.com)
Aqua" means water, so inside an aquarium you will find a miniature of water environment. (earthbuddies.net)
Oxide2
The dichromate is then reduced with carbon to chromium sesquioxide, Cr2O3, and that oxide in turn is reduced with aluminum to give the chromium metal. (mathisfunforum.com)
Certain oxidizing agents produce a thin unreactive oxide layer on the metal, rendering it passive also to dilute mineral acids, such as sulfuric, nitric, or cold aqua regia. (mathisfunforum.com)
Organism2
natural seawater contain many undesirable organism and pollutant. (edu.vn)
Likewise, expect your pH to be lowest in the early morning, after the ligths have been off all night, and photosynthetic organism have been consuming O2 and giving off CO2 throughout the night. (seahorse.com)
One of such effects not fully explainable by chemistry, yet officially utilized by some non-Western ally nations, is prolonged "water structure", or/ "activated" electrical charge holding capacity of ions in water. (powershow.com)
At ordinary temperatures the metal shows no reaction to seawater or to wet or dry air. (mathisfunforum.com)
Photosynthesis3
The respiration process of plankton present in water also adds carbon dioxide into the water, but the photosynthesis process usually offsets the amount of carbon dioxide produced through respiration. (worldwideaquaculture.com)
IF you have an indoor pond, the only way you can supply enough oxygen to your fish is through a water pump and a mechanical aerator because there is no plankton present in water for the photosynthesis process to take place. (worldwideaquaculture.com)
This is related to photosynthesis and the fact that zooanthellae and green plants consume CO2 and produce O2 when there is adequate light, but reverse that process in the dark, consuming O2 and giving off CO2. (seahorse.com)
Water quality parameters1
Redox levels, available calcium and other water quality parameters are affected in similar ways. (seahorse.com)
Oxygen3
The bond between a water molecule and the metal ion is a dative covalent bond, with the oxygen atom donating both electrons to the bond. (wikipedia.org)
Various chemicals present in water, the acidity and alkalinity of water, salinity, pH levels and dissolved substances can influence chemical reactions in water and can affect your productivity. (worldwideaquaculture.com)
Metal5
A metal ion in aqueous solution or aqua ion is a cation, dissolved in water, of chemical formula [M(H2O)n]z+. (wikipedia.org)
The strength of the M-O bond tends to increase with the charge and decrease as the size of the metal ion increases. (wikipedia.org)
Metal aqua ions are always accompanied in solution by solvated anions, but much less is known about anion solvation than about cation solvation. (wikipedia.org)
Others are accepted but only for certain use ElectroOsmosis/Poration, Metal ion, 3chamber electrolysis, Vacuum superheated steam, Steam eductor etc. (powershow.com)
chelating agent that works by binding to metal ions and thereby inactivating them. (lisaliseblog.com)
Species3
a similar problem affects astatine, which forms a cationic species, but whether that is an aqua cation is unknown. (wikipedia.org)
In the +6 oxidation state, the most important species formed by chromium are the chromate, and dichromate, ions. (mathisfunforum.com)
There are several mercury species present in crude oil and gas condensates that are seldom accounted for in routine analysis. (researchgate.net)
Structures1
No experimental information regarding aqua ion structures Most chemical elements are metallic. (wikipedia.org)
Except for: 3.6 times more iron, 2 times more phosphate, 33% less bromide, some of the lowest levels of essential calcium and unbelievable variations from batch to batch vs. NSW. (aquacraft.net)
In short, it's important to check your pH and calcium readings at the same time every day (otherwise you may just be seeing normal daily variations in pH). (seahorse.com)
Stable2
Ok, I have been able to keep my PH stable and my calcium is up. (seahorse.com)
To maintain a stable environment it is important that the calcium content should not fluctuate by more than 15 mg/L from the optimum range of 420 - 450 mg/L so regular testing should be carried out. (aquasd.com)
Form4
Compounds of the metallic elements usually form simple aqua ions with the formula [M(H2O)n]z+ in low oxidation states. (wikipedia.org)
Some elements, such as tin and antimony, are clearly metals, but form only covalent compounds in the highest oxidation states: their aqua cations are restricted to their lower oxidation states. (wikipedia.org)
Visiting the beach provides an excellent opportunity to soak up some sun and enjoy the benefits of vitamin D. The sun's rays are a natural source of this essential vitamin, which plays a crucial role in strengthening our immune system, regulating calcium in the body, and promoting healthy bone growth.

The Salifert Phosphate test kit detects, in less than 5 seconds, the level of phosphate present. (aquasd.com)
Levels3
Yes, your calcium levels may be dropping faster than expected because the calcium levels have been deeply to for so long. (seahorse.com)
Once your calcium levels have stabilized, your pH will also be more resistant to abrupt changes as well, and vice versa. (seahorse.com)
2. Midori Prize is an annual international prize given to an individual for outstanding contribution to the conservation and sustainable use of biodiversity at global, regional or local levels. (dsguruji.com)
Means1
This means that any calcium test used should have an accuracy of significantly less than 15mg/L otherwise it will be difficult to monitor such fluctuations. (aquasd.com)
Important2
Calcium also fulfills many important biological functions. (aquasd.com)
This step is pretty important since you might find some soil or water drop sticking inside the container that will give your terrarium a bad look. (earthbuddies.net)
Time3
So be sure to monitor your pH and calcium the same time of day when you perform your test, Christine. (seahorse.com)
The Salifert test kit does not suffer from such interference and gives accurate and quick results with a total testing time of less than 3 minutes. (aquasd.com)
