sy: A sample of a substance whose only oxidizable material is tin in the +2 state, is titrated with a dichromate solution that was prepared by dissolving 1.226 6 of KyCr, o, in enough water to give a volume of 250.00 cm3. A. 0.0821 g sample of the substance required a volume of 23.90 cm3 of the titrant to reach the equivalence point. The product of the oxidation of the tin in the +2 state is to tin In the +4 state. The reduction product of the dichromate , is chromium in the +3 state. Calculate the % of tin in the substance. (NB: Assume the reaction to take place in acidic medium)
