Problem 66P

Use the half-reaction method to balance each redox reaction occurring in acidic aqueous solution.

(a) I−(aq) + NO2− (aq) → I2(s) + NO(g)

(b) BrO3− (aq) + N2H4(g) → Br− (aq) + N2(g)

(c) NO3−(aq) + Sn2+ (aq) → Sn4+ (aq) + NO(g)

Step-by-Step Solution:
Step 2 of 3

Solution 66P:

Srep 1:

(a) I−(aq) + NO2− (aq) → I2(s) + NO(g)

The balanced chemical equation is

2 I−(aq) + 2NO2− (aq) + 4H+ (aq)→ I2(s) + 2NO(g) + 2H2O(l)

Step 2:

(b) BrO3− (aq) + N2H4(g) → Br− (aq) + N2(g)

The balanced chemical equation is

2BrO3− (aq) + 3N2H4(g) →2 Br− (aq) + 3N2(g) + 6H2O(l)
