A more eligible preparation is the molybdate of baryta, produced by mixing solutions of molybdate of potash and acetate of baryta.
molybdate of ammonium is the salt principally used in dyeing.
As long as the solution contains lead, the addition of the molybdate solution causes a precipitation of white lead molybdate.
A blue precipitate falls, which is a molybdate of molybdic oxide, hydrated, and abundantly soluble in water.
The fluid acquires a yellow coloration when boiled with a solution of molybdate of ammonia.
The solution containing the molybdate is neutralised and treated with an excess of mercurous nitrate.
