A complex between sodium nitroprusside (NP) and acetaldehyde of 1:1 in aqueous solution of pH 10 has been prepared and used as an analytical reagent for the spectrophotometric determination of sulfite and nitrite ions. Nitrite ion can be titrated against sulfite ion and vise versa in equivalent amounts with high accuracy in the presence of the acetaldehyde complex of nitroprusside as a carrier using a potentiometric titration technique. 9 references, 3 figures, 2 tables.
