Abstract

An improved solution for reduction of oxide includes an oxide reduction agent and a halide or pseudo halide. The solution may be used to enhance a catholyte for an electrochemical system and process for regenerating reducing agents used in ancillary chemical or electrochemical processes such as restoring solderability in components having recalcitrant oxides. Such a system and process employs a cathode, an anode, and an electrolyte system that is separated by a semipermeable ionic barrier into the catholyte and an anolyte. The catholyte includes the reduced member of a redox couple, which can be regenerated electrochemically.
