The plumbic seleniate is suspended in water and decomposed by means of a current of sulphuretted hydrogen. |
The residue dissolved in water is mixed with a solution of plumbic nitrate, an insoluble plumbic seleniate being precipitated. |
Plumbic acetate gives a purplish-red precipitate, mercuric cyanide a blue one, the supernatant liquid being also blue. |
The only thing that is known, is that they add plumbic ochre into the composition. |
