Abstract
A process for electrolysis in a membrane electrolytic cell comprises feeding a concentrated alkali metal halide brine containing complex-forming elements and silica at a pH of from about 4 to about 12 to the cell. The alkali metal halide brine is electrolyzed under conditions which maintain the pH of the alkali metal halide brine at a value above about 3.5.
