Phosphate and ammonium molybdate reaction
WebFeb 1, 2011 · (a) In the acidified reaction solutions of phosphate, there are no strong aromatic interactions in the complexes of each hydrophobic amine of interference with phosphomolybdate, and negligible ternary complexes of such a hydrophobic amine, MLG and phosphomolybdate. WebAmmonium molybdate has been used to prepare phosphomolybdates. (NH 4) 2 MoO 4 was used as an analytical reagent for quantitative analysis of phosphates, silicates, arsenates and lead in their aqueous solutions. At saturated concentration, (NH 4) 2 MoO 4 was used to perform cryo-negative staining and as a negative stain in biological electron microscopy. …
