General description
Ammonium molybdate can be prepared by dissolving molybdenum trioxide in ammonia.
Application
Ammonium molybdate has been used to prepare phosphomolybdates. (NH4)2MoO4 was used as an analytical reagent for quantitative analysis of phosphates, silicates, arsenates and lead in their aqueous solutions. At saturated concentration, (NH4)2MoO4 was used to perform cryo-negative staining and as a negative stain in biological electron microscopy. Ammonium molybdate was used in study of crystallisation of cell-free-expressed membrane proteins.
