Polarographic Study of the Reaction between Ce(IV) and thiocyanate II

Reaction between Ce(IV) and SCN‐ has been studied polarographically. At low concentration of SCN‐, Ce(IV) is reduced to Ce(III) with resultant formation of SO or SO , involving the intermediate formation of thiocyanogen free radical. However, in presence of excess of SCN‐ it is likely that thiocyanogen or it's polymerised form is formed during the reaction, predominantly.
