solution of KCN. The precipitated K2Pt(CN)4·3H2O is filtered off with suction. If it is to be used for preparing
the barium salt, it is dissolved in water and treated with a concentrated aqueous solution of BaCl2. The precipitated BaPt(CN)4·4H2O is filtered off with suction and washed with cold water.
