Problem 60EDetermine whether or not each metal dissolves in . For those metals that dodissolve, write a balanced redox equation for the reaction that occurs.a. Aub. Cr Step by step solutionStep 1 of 2(a)Iodic acid can oxidize metals through the reduction half -reaction.The reduction half reaction of iodic acid is as follows.The substance with large positive reduction half - cell potentials show a strong tendency to gainelectrons and act as a strong oxidizing agents.Hence, iodic acid can oxidize metals that have smaller positive reduction half - potentials than1.20 V.The standard reduction potential and reduction half reactions of “Au” are as follows.The reduction potential value of gold is larger than the 1.20 V. Hence gold cannot be oxidizedby iodic acid.Therefore, “Au” does not dissolve in the ._______________________________________________________________________
