Phosphate and ammonium molybdate reaction

WebWhen phosphates react with ammonium molybdate in strongly acid solution, a yellow colour results and then a precipitate of ammonium molydatophosphate is formed. This reaction … WebA sample containing the phosphate is mixed with an acid solution of Mo VI, for example ammonium molybdate, to produce PMo 12O3− 40, which has an α- Keggin structure. This anion is then reduced by, for example, ascorbic acid or SnCl 2, to form the blue coloured β-keggin ion, PMo 12O7− 40. [5]
