Abstract: A detailed analysis of two samples of sodium bismuthate (Riedel and E. Merck) shows that they have a water molecule which is eliminated by heating. Sodium and bismuth contents correspond to an atom of each per mol of NaBiO3. A modified iodometric method for the determination of bismuth(V) has been described which eliminates the interference from bismuth(III), by complexation with EDTA. The bismuth(V)content in the two samples was about 90% and thus there appears to be about 10% Bi(III) in the samples perhaps in the form of NaBiO2.
