Silver chromate is sparingly soluble in aqueous solutions. the ksp of ag2cro4 is 1.12 * 10-12 m3. what is the solubility (in mol/l) of silver chromate

6.542 x 10⁻⁵ mol/L.

Explanation:

Co (OH) ₂ dissociates in solution according to the equation:

Ag₂CrO₄ → 2Ag⁺ + CrO₄²⁻.

∵ Ksp = [Ag⁺]²[CrO₄²⁻] = (2s) ² (s) = 4s³.

∴ 4s³ = 1.12 x 10⁻¹².

∴ s³ = 1.12 x 10⁻¹²/4 = 2.80 x 10⁻¹³.

∴ s = ∛ (2.80 x 10⁻¹³) = 6.542 x 10⁻⁵ mol/L.
