Complexes and salts of metal cations in aqueous solutions are electrodialytically converted into a solution of acids substantially free of metal cations and insoluble metal hydroxides. Metal cations are insolubilized by hydroxyl ions formed in a catholyte while anions are electrotransported from the catholyte and converted into a solution of acids by hydrogen ions formed in an anolyte of an electrodialytic process. The conversion process is carried out electrically without the electrotransport of metal cations and is especially useful for reforming solutions of acids that form complexes when etching and finishing metal surfaces.
