✦ Synopsis

Reagent solution. A i % solution of the reagent was obtained by dissolving I,O g of recrystallized o-phenylenediamine (m.p. lO2 ~ in IOO ml water containing a little acetic acid. Bu]]er solution. Buffer solutions of pH range 3.42--5.89 were obtained by mixing o.2 N sodium acetate with 0.2 N acetic acid in varying quantities 6.

Other reagents. Solutions of other platinum metals and common ions were prepared in an identical way as described in a previous paperL
