8 PLATINUM CHLORIDE forms with hydrochlorides of the alka- 

 loids double salts which arc mostly soluble with difficulty in water ; 

 others however, are readily soluble, and are consequently not precipi- 

 tated or are only deposited from concentrated solutions. The formulas 

 of these double salts are usually (NR'HCl), PtCl„or N.,R(HCl),-PtCl„ 

 so that the ratio of nitrogen to platinum is No : Pt, but there are a tew 

 exceptions to this rule. .... 



Platinum chloride is reduced by some substances, and occasionally gives 

 colour effects.
