Solubility Product (K) of Mn(OH)2

Half Reactions Used:
Mn(OH)2(s) ⇌ Mn2+(aq) + 2OH-(aq)

Mn(OH)2(s) → Mn(s) + 2OH-(aq) [E° = -1.59 V]
Mn2+(aq) + 2e- → Mn(s) [E° = -1.18 V]

Step 1: Calculate the Standard Cell Potential (E°cell)
E°cell = E°reduction + E°oxidation
E°cell = (-1.18) - (-1.59)
E°cell = 0.41 V

Step 2: Calculate the Equilibrium Constant (K)
E°cell = (0.0592/n) log K
0.41 V = (0.0592/2) log K
log K = 13.91
K = antilog (13.91)
K = 1.8 x 10^-14

Therefore, the solubility product (K) of Mn(OH)2 is 1.8 x 10^-14.

Answer: [C] 1.8×10^-14
