Chromate (CrO42-) - Structure, Molecular Mass, Properties and …
网页What is Chromate? Chromates are the salts of chromic acid which contains the chromate anion with the chemical formula CrO42– and usually have an intense yellow color. Chromate is the oxoanion which results from the removal of protons from chromic acid. It is also called chromium oxoanion or divalent inorganic anions.

Chromate - Simple English Wikipedia, the free encyclopedia
网页Chromate is an ion that contains one chromium atom (in its +6 oxidation state) and four oxide atoms. Its formula is CrO 4. Its overall charge is -2. Dichromate is similar, but it contains two chromium atoms and seven oxide atoms (therefore, Cr 2 O 7). Chromate and dichromate are strongly oxidizing in acidic conditions, but weakly oxidizing in ...
Chromate and dichromate - Wikipedia
网页The hydrogen chromate ion, HCrO 4 −, is a weak acid: HCrO − 4 ⇌ CrO 2− 4 + H +; pK a ≈ 5.9. It is also in equilibrium with the dichromate ion: 2 HCrO − 4 ⇌ Cr 2 O 2− 7 + H 2 O. This equilibrium does not involve a change in hydrogen ion concentration, which would predict that the equilibrium is independent of pH.

网页Define ionic and molecular (covalent) compounds. Predict the type of compound formed from elements based on their location within the periodic table. Determine formulas for simple ionic compounds. In ordinary chemical reactions, the nucleus of each atom (and thus the identity of the element) remains unchanged.
