Cerium(IV) ion is a strong oxidizing agent that accepts one electron to produce cerium(III) ion:

A solution containing an unknown concentration of Sn²⁺ ions was titrated with a solution containing Ce⁴⁺ ions, which oxidize the Sn²⁺ ions to Sn⁴⁺ ions. In one titration 1.00 L of the unknown solution required 46.45 mL of a 0.1050 M Ce⁴⁺ solution to reach the stoichiometric point. Calculate the concentration of Sn²⁺ ions in the unknown solution.
