How to dispose of chromium salts?
If chromium metal or insoluble chromium salts are spilled, the following steps should be taken: 1. Remove all ignition sources where metallic chromium has been spilled. 2. Ventilate area of spill. 3) Collect spilled material in the most convenient and safe manner and deposit in sealed containers for reclamation or for disposal in a secured sanitary landfill. Liquid containing chromium metal or insoluble chromium salts should be absorbed in vermiculite, dry sand, earth, or a similar material. / Chromium metal and insoluble chromium salts/

What is the reaction of acidic salts?
The resulting solutions contain moderate to high concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Many of these compounds catalyze organic reactions.

What is the most useful source of chromium sulfate?
The most useful source of chromium (III) sulfate are the Cr (III) wastes from the chromate oxidation of various organic compounds. Anthroquinone and quinone are produced on large scale by treatment of anthracene and phenol with chromic acid. A chromium (III) oxide coproduct is generated which is readily extracted into sulfuric acid.
How is chromium sulfate produced?
Basic chromium (III) sulfate. Basic chromium sulfate is produced from chromate salts by reduction with sulfur dioxide, although other methods exist. The reduction could formally be written: Since 33% of the anion charges are due to hydroxy ions the basicity is 33% (but in tanning jargon it is known as 33% reduced).
Why is sodium sulfate left in tanning products?
The sodium sulfate is often left in the technical product since it is inert with respect to the tanning process. It is important to fully reduce the hexavalent chromium to trivalent since the hexavalent is more likely to cause health problems for tanners and leather consumers.
Is chromium sulfate hydroxide?
A variety of other chromium (VI) sulfates are known, but also contain hydroxide or oxide ligands. Most important commercially is basic chromium sulfate, which is thought to be [Cr 2 (H 2 O) 6 (OH) 4 ]SO 4 (CAS#39380-78-4). It results from the partial neutralization of the hexahydrates.
Is Cr2 soluble in water?
We want to use Chromic Sulphate (Cr2 (SO4)3.6H2O) to contaminate soil, however we found it not to be soluble in water while according the literature and tanning practices this should be soluble in water. How can this be?
Is chromic sulfate soluble in alcohol?
The anhydrous salt of chromic sulfate is insoluble in water and acids but dissolves to form complexes when reducing agents are added; the hydrated salts are soluble in water; the pentadecahydrate is insoluble in alcohol, but the octadecahydrate dissolves in alcohol. Your chromic sulphate is probably the anhydrous and not the hydrated form. Tie up with the company. Just a little mix-up i want to believe.
What is the oxidation state of chromium?
Since ionic bonds between ions are mostly "exchanging superscripts for subscripts", we can already glean that the oxidation state for chromium is +3 . (2) Long answer: Most often than not, the oxidation state of oxygen is -2 (mainly due to it being a member of Group 6 in the periodic table and it being electronegative).
Which element has two oxidation states?
Substituting the values of oxidation states in the formula, Addendum The element chromium, can only have two oxidation states: Cr+3 and Cr+6.
