PLATINUM CHLORIDE forms with hydrocblorides of the alka- loids double salts, which are mostly soluble with difficulty in water; others, however, are readily soluble, and are consequeutly not precipi- tated, or are only deposited from concentrated solutions. The formulae of these double salts are usually (NR-HC1)2 PtCl4,or N2R (HCl)2 PtCl4, so that the ratio of nitrogen to platinum is No : Pt, but there are a few exceptions to this rule. Platinum chloride is reduced by some substances, and occasionally gives colour effects. I. Alkaloids precipi- tated or causing re- duction (pp. unless otherwise stated). Abrotine, df. sol.
