Chapter 15, Problem 64APP

Write the balanced half-reactions and a balanced redox equation for each of the following reactions in acidic solution: $(15.2)$

a. ${\text{Sn}}^{2+}(aq)+{\text{IO}}_4^{-}(aq)\to {\text{Sn}}^{4+}(aq)+{\text{I}}^{-}(aq)$

b. ${\text{S}}_2{\text{O}}_3{}^{2-}(aq)+{\text{I}}_2(s)\to {\text{S}}_4{\text{O}}_6{}^{2-}(aq)+{\text{I}}^{-}(aq)$

c. $\text{Mg}(s)+{\text{VO}}_4{}^{3-}(aq)\to {\text{Mg}}^{2+}(aq)+{\text{V}}^{2+}(aq)$

d. $\text{Al}(s)+{\text{Cr}}_2{\text{O}}_7{}^{2-}(aq)\to {\text{Al}}^{3+}(aq)+{\text{Cr}}^{3+}(aq)$
