Summary The reaction of tellurite with manganate solution is not rapid in 0.2–0.5 N NaOH but is enhanced at higher alkalinities. Titration of tellurite with manganate gives accurate results. The titration of manganate with quadrivalent tellurium gives good results both in the presence or absence of telluric acid but the accuracy is better in the presence of telluric acid than in its absence. In the titration curve of manganate the step corresponding to hypomanganate is observed only in the presence of telluric acid and above 1 N NaOH.
