WebJan 24, 2024 · In a dilute orthophosphate solution, ammonium molybdate reacts under acid conditions to form the heteropoly acid, molybdophosphoric acid. In the presence of vanadium, yellow vanadomolybdo-phosphoric acid is formed. The intensity of the yellow color is proportional to phosphate concentration. WebSodium nitrite is used as an accelerator in some zinc phosphate solutions. It is usually controlled at 1 point. Before the test for sodium nitrite is run, the phosphate solution should be checked for the absence of iron. This is done by dipping a strip of iron-test paper in the phosphate solution.
