"But I've seen powdered chlorate of potash," interposed Tom Reade, who was always in search of information. "Yes," admitted the druggist. "I can show you, at my store, about ten pounds of the powdered chlorate." "Then how do they get it into a powder, sir?" pressed Tom. "Do the manufacturers grind it between big millstones?"
Boil the finely divided substance with about one-eighth its bulk of pure hydrochloric acid; add from time to time potassic chlorate until the solids are reduced to a straw-yellow fluid. Treat this with excess of bisulphate of sodium, then saturate with sulphuretted hydrogen until metals are thrown down as sulphides. These may be collected and tested.
In some processes the electrolysis affords directly an alkaline hypochlorite or a chlorate, the former being of wide commercial use as a bleaching agent in textile works and in the paper industry. The same process employed in the electrolysis of sodium salts is used in the case of magnesium and calcium.
The centre one, I venture, contained sulphuric acid and chlorate of potash separated by a close-packed wad of cotton wool. Then the two tubes on each side probably contained the powder, and perhaps the outside tubes were filled with spirits of turpentine.
