Silver Molybdates

There have been described normal silver molybdate, an acid salt 2Ag₂O.5MoO₃, and a tetramolybdate Ag₂O.4MoO₃.6H₂O, besides the ammoniacal salt Ag₂MoO₄.4NH₃ (which is prepared either by absorption of ammonia by the dry salt, or by evaporating an ammoniacal solution of the molybdate with lime and ammonium chloride) and a cerimolybdate.
