description	Electrochemical devices and methods for acid and base generation are disclosed. A source of purified water is fluidly connected to at least one compartment of the device. A source of an ionic species, such as an acid or base precursor, is also provided to at least one compartment of the device. An applied electrical field promotes ion transport across selective membranes which at least partially define the compartments. The purified water may be dissociated into hydronium and hydroxyl ions in an electrolyzing compartment of the device. Acid and/or base product streams may be recovered as desired at outlets of the various compartments. In some embodiments, a bipolar membrane may be used to split water in place of the electrolyzing compartment.
