Question

Balance the equations below assuming they occur in a basic solution.

(a) SO₃₂⁻ (aq) + Cu(OH)₂(s) → SO₄₂⁻ (aq) + Cu(OH)(s)
(b) O₂(g) + Mn(OH)₂ (8) + MnO₂(s)
(c) NO₃- (aq) + H₂(g) → NO(g)
(d) Al(s) + CrO₄₂⁻ (aq) + Al(OH)₃(s) + Cr(OH)₄ - (aq)

Answer 1

To balance the given equations in a basic solution: (a) 2SO3^2- (aq) + Cu(OH)2 (s) → SO4^2- (aq) + Cu(OH) (s), (b) 2Mn(OH)2 (s) → MnO2 (s), (c) 2NO3- (aq) + H2 (g) → 2NO (g), (d) 4Al (s) + 4CrO4^2- (aq) + 4Al(OH)3 (s) + 4Cr(OH)4^- (aq)

Step-by-step explanation:

To balance the given equations assuming they occur in a basic solution:

1. (a) 2SO32- (aq) + Cu(OH)2 (s) → SO42- (aq) + Cu(OH) (s)
2. (b) 2Mn(OH)2 (s) → MnO2 (s)
3. (c) 2NO3- (aq) + H2 (g) → 2NO (g)
4. (d) 4Al (s) + 4CrO42- (aq) + 4Al(OH)3 (s) + 4Cr(OH)4- (aq)
