Abstract
The production of acid and base is effected by the electrolysis of a metal halide salt solution across an ion-exchange membrane. The base is removed directly from the cathode and the hydrogen and halogen gases produced at the electrodes are reacted in a catalytic column to form the acid. This gas is absorbed by water to form an aqueous hydrogen halide acid solution. Such a system can be operated automatically and on a small scale.
