✦ Synopsis

The electrodialytic water dissociation process employing bipolar membranes has been used successfully for obtaining acids and alkalies from salts. Earlier reports by us described the preparation of bipolar membranes and their applications in converting sodium sulphate into sulphuric acid and sodium hydroxide; sodium acetate into acetic acid and sodium hydroxide [G. S. Trivedi et al., React. Funct. Polym. 28 (1996) 243; Ibid: 32 (1997) 209]. In this paper as an extension of our earlier published works the experimental results on the conversion of sodium phosphate to phosphoric acid and sodium hydroxide under different experimental conditions are described.
