The chromate formula is one of the common formulas that is seen often in chemistry. The formula represents the chromate ion which is one of several polyatomic ions used often in the formation of insoluble salts.
As per the definition, chromate is a chromium oxoanion and a divalent inorganic anion which is formed by the removal of two protons in chromic acid. It acts as a strong oxidising agent and is usually a conjugate base of a hydrogenchromate.
