Solubility of M₂S salt is 3.5 ˣ 10⁻⁶ then find out solubility product
Options
(a) 1.7 ˣ 10⁻⁶
(b) 1.7 ˣ 10⁻¹⁶
(c) 1.7 ˣ 10⁻¹⁸
(d) 1.7 ˣ 10⁻¹²
Correct Answer:
1.7 ˣ 10⁻¹⁶
Explanation:
For reaction. M₂S ⇌ 2M⁺ + S²⁻.
Let solubility = 3.5×10⁻⁶.
Solubility product, K(sp) = [M⁺]²[S²⁻]
= (2s)² s = 4s³
= 4x(3.5×10⁻⁶)³
= 1.7×10⁻¹⁶
