Solution: Balance the following redox reactions occurring in basic solution.NO2−(aq) + Al(s) → NH 3(g) + AlO2−(aq)a. NO2−(aq) + H2O(l) + 2Al(s) + OH−(aq) → NH3(g) + 2AlO2−(aq)b. NO2−(aq) + H2O(l) + 2Al(s) + OH−

Problem

Balance the following redox reactions occurring in basic solution.

NO2(aq) + Al(s) → NH 3(g) + AlO2(aq)

a. NO2(aq) + H2O(l) + 2Al(s) + OH(aq) → NH3(g) + 2AlO2−(aq)

b. NO2(aq) + H2O(l) + 2Al(s) + OH(aq) → 2NH3(g) + 2AlO2(aq)

c. NO2(aq) + H2O(l) + Al(s) + 2OH(aq) → 2NH3(g) + AlO2(aq)

d. NO2(aq) + 2H2O(l) + Al(s) + 2OH(aq) → NH3(g) + AlO2(aq)
