Silver nitrate, AgN03. Other Liquid Reagents. Sulphuretted hydrogen water, prepared by saturating cold distilled water, previously well boiled, with hydrogen sulphide. Yellow ammonium sulphide, which may be bought, or it may be prepared by saturating liquid ammonia with sulphu- retted hydrogen and digesting the colourless liquid, (NH4)2S, with a little powdered sulphur, so as to form the yellow polysulphide. Alcohol at 96 per cent. Ether, chloroform, and petroleum ether may be bought.
