Summary
-
1.
Electrolysis of NaClO3 in H2O18 under conditions such that exchange is excluded leads initially to passage of the oxygen of the water into ClO −3 alone; the oxygen is later retransferred to the ClO4/− so that complete conversion of chlorate to perchlorate gives a product containing 25.5–28% water oxygen.

2.
The data obtained here makes it possible to exclude the possibility of a mechanism involving atomic oxygen or the ClO .3 and ·OH radicals. These data are consistent with a suggestion made earlier on the basis of electrochemical measurements, namely, that the ClO −3 ions initially discharge on the anode to form an intermediate compound which reacts with water to give ClO −3 and ClO −4 .
