Microchimica Acta Aims and scope Submit manuscript

Summary

Standard copper sulphate solution has been successfully used for the direct titration of dilute solutions (≦0.05N) of thiosulphate, sulphite or tin(II) in presence of potassium iodide (5–7%) and starch. The method is sensitive and precise.
