The solubility of CuBr is 2 ˣ 10⁻⁴ mol/L at 25⁰C. The Ksp value for CuBr is
Options
(a) 4 ˣ 10⁻⁸ mol² L⁻²
(b) 4 ˣ 10⁻⁴mol² L⁻²
(c) 4 ˣ 10⁻¹¹mol² L⁻²
(d) 4 ˣ 10⁻¹⁵mol² L⁻²
Correct Answer:
4 ˣ 10⁻⁸ mol² L⁻²
Explanation:
CuBr → Cu⁺ + Br⁻,
Solubility of CuBr is 2×10⁻⁴ mol L⁻¹ ,
therefore, solubility of Cu⁺ = Br⁻ = 2*10⁻⁴ mol L⁻¹ .
⇒ Solubility product = 2*10⁻⁴ * 2 * 10⁻⁴, 4*10⁻⁸ mol²L⁻².
