8.21 The ion is unstable in solution and undergoes disproportionation to give , and ion. Write a balanced ionic equation for the reaction
The base equation
write oxidation half with their oxidation state
Balance the charge on by adding 1 on RHS side. To balance charge add ions on RHS side and then for oxygen balance add molecule on LHS side.
balancing the reduction half by adding 1 on LHS side
Add both balanced reduction half and oxidation half
