An apparatus is disclosed for generating an acidified aqueous salt solution and an aqueous base in a multichamber two-compartment electrodialytic water splitter which comprises alternating bipolar and first cation permselective membranes and at least one additional substantially non-porous, water-swollen cation permselective or neutral membrane disposed between a cation face of the bipolar membrane and a face of said first cation membrane thereby defining at least two acid compartments and a base compartment positioned between an anode and a cathode. The method comprises the steps of: (a) introducing a liquid comprising water to the base introducing a liquid comprising an aqueous soluble salt to a first acid compartment adjacent the base compartment (c) serially transferring the liquid comprising the aqueous soluble salt from the first acid compartment to a second acid compartment adjacent the first acid compartment (d) passing direct current through said water splitter thereby adding hydrogen ions to the first and second acid compartments, metal cations from the acid compartments to the base compartment, and adding hydroxide ions to the liquid comprising water in the base compartment; (e) withdrawing a liquid comprising aqueous base from the base compartment; and (f) withdrawing an acidified aqueous soluble salt from the second acid compartment.
