Solution: One way to determine the concentration of hypochlorite ions (CIO-) in solution is by first reacting them with I- ions. Under acidic conditions the products of this reaction are I_2 and Cl^- ions. Then

Problem

One way to determine the concentration of hypochlorite ions (CIO-) in solution is by first reacting them with I- ions. Under acidic conditions the products of this reaction are I_2 and Cl^- ions. Then the l2 produced in the first reaction is titrated with a solution of thiosulfate ions (S2O32-). The products of the titration reaction are S4O62- and I- ions. 

Write net ionic equations for these two reactions. Write the first one in the upper box. Do not include phases.
