Extraction titrimetric determination of copper.
Lead xanthate undergoes a quantitative, stoichiometric and fast exchange reaction with copper(II), even near the equivalence point, making it a suitable reagent for an extraction titration of copper. Many other metal ions do not participate in exchange reactions with lead xanthate. making this method selective for copper.
