An unknown metal hypochlorite salt, M(ClO)2, is subjected to analysis by iodometric titration: the salt is dissolved in dilute sulfuric acid, treated with excess aqueous KI, and then titrated with Na2S2O2 in the same manner as in your experiment. The unknown metal ion (M^2+) is completely uncreative in the titration. However, all of the hypochlorite ion bonded to the metal reacts completely with Na2S2O2. Iodometric titration of an acidified 0.0499 g sample of M(ClO)2 required 28.42 ml of 0.05521 mol/L Na2S2O2 to reach the equivalence point. What it the identity of metal M?
