Amperometric determination ot bivalent tin with dichromate

Abstract

An amperometric determination of tin with potassium dichromate has been described. The advantage of the cathodic polarograms of Cr2O27- and Sn2+ in formate media was taken and titrations were performed at -0.8 V vs. S.C.E. at pH ≈3.0. It is shown that tin upto 10 mg may be determined accurately within the limits of experimental errors. © 1963 Springer-Verlag.
