other limitations and requirements: free from chromate ion.
Under acidic conditions, the chromate ion is protonated to form chromic acid, which does not produce the precipitate at the end point.
Chromate salts contain the chromate anion, CrO 2− 4 .
While (for example) CrO42− can also inhibit corrosion, it requires a concentration ten times as high.
