An electrolytic cell for the production of acid water which performs simple
operation to produce acid water without complicated control over the
concentration of hydrochloric acid to be added or precipitation of
alkaline earth metal salts, which are disadvantages of the prior art
electrolysis for the production of acid water. An electrolytic cell for
the production of acid water, which comprises a power supply for applying
a voltage across an anode chamber and a cathode chamber partitioned by an
ion-exchange membrane. The anode in the anode chamber is disposed in close
contact with the ion-exchange membrane. The electrolytic cell further
comprises means for supplying an aqueous solution of hydrochloric acid and
water to the cathode chamber and the anode chamber, respectively.
Hydrochloric acid is not directly added to the anode chamber but
indirectly added to the anode chamber by diffusing through the
ion-exchange membrane. In this manner, hydrochloric acid is uniformly
dispersed into the anode chamber by diffusing through the ion-exchange
membrane. Thus, the need for controlling concentration is eliminated.
Furthermore, because both the catholyte and anolyte are kept acidic, no
precipitation of metal salts occurs.
