The laws of selective dissolution of an electronegative component A from A-B alloy at constant potential are analyzed while allowing for a multistep mechanism of the dissolution of A. The expression obtained for the time dependence of the overall dissolution rate of A from the alloy is analyzed for the case where the concentration of A on the alloy surface is constant while the rate of the step A in equilibrium A /SUP n1+/ + n/sub 1/e is much higher than that of the step A /SUP n1+/ in equilibrium A /SUP n+/ + n/sub 2/e. The approach developed is used to study the laws of In dissolution from In-Sn alloy (17 atom % of In) in chloride solution.
