# Problem: Balance each of the following equations according to the half-reaction method:(c) CN−(aq) + ClO2(aq) ⟶ CNO−(aq) + Cl−(aq) (in acid)

###### FREE Expert Solution

CN(aq) + ClO2(aq) CNO(aq) + Cl(aq)

Step 1. Separate the whole reaction into half-reactions

CN(aq) CNO(aq)

ClO2(aq) Cl(aq)

Step 2. Balance the non-hydrogen and non-oxygen elements first

CN(aq) CNO(aq)

ClO2(aq) Cl(aq)

Step 3. Balance oxygen by adding H2O to the side that needs oxygen (1 O: 1 H2O)

CN(aq) + H2O(l) CNO(aq)

ClO2(aq) Cl(aq) + 2 H2O(l)

Step 4. Balance hydrogen by adding H+ to the side that needs hydrogen (1 H: 1 H+)

CN(aq) + H2O(l) CNO(aq) + 2 H+(aq)

ClO2(aq) + 4 H+(aq) Cl(aq) + 2 H2O(l)
