The chromous-chromic reaction is highly unstable because of the high instability of the chromous salt. This redox couple is only stable when the concentration of the chromous salt is 5 to 10 times higher than that of the chromic salt. This reaction has been studied60 in 1.0 JV H2S04, and the plots of AFoo/ V versus co-1/2 are given in Fig. 9. The value of a is 0.47 and fc° = 2 x 10-3 cm/s. The results (Table 3) are comparable to those obtained by direct current polarography. 

Studies using a differential-pulse polarographic technique, which is recommended in place of classical direct current polarography, yielded the following results. For...
