Problem: Balance the following skeleton reactions and identify the oxidizing and reducing agents:(a) ClO3−(aq) + I−(aq) ⟶ I2(s) + Cl−(aq) [acidic]

FREE Expert Solution

Step 1. Separate the whole reaction into half-reactions

ClO3(aq) Cl(aq)

I(aq) I2(s)


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

ClO3(aq) Cl(aq)

2 I(aq) I2(s)


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

ClO3(aq) Cl(aq) + 3 H2O(l)

2 I(aq) I2(s)


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