ABSTRACT:
A method for producing a metal salt by electrolysis in an electrolytic cell comprising an anode compartment and a cathode compartment partitioned by a diaphragm, disposing in the anode compartment a metal anode soluble in the aqueous solution, and conducting electrolysis to dissolve the metal anode, wherein the diaphragm is a fluorinated anion exchange membrane made of a copolymer having repeating units of the formula: ##STR1## wherein X is F or CF.sub.3, l is an integer of from 0 to 5, m is 0 or 1, n is an integer of 1 to 5, each of p and q is a positive number and the ratio of p/q is from 2 to 16, and Y is a group involving a quaternary ammonium group.
