Calculate the solubility (in g/l) of silver chromate in water at 25°c if the ksp for ag2cro4 is 1.1 × 10-12. 2.7 × 10-2 g/l 2.2 × 10-2 g/l 3.4 × 10-2 g/l 3.5 × 10-4 g/l

Answer is: solubility of silver chromate is 2.2 × 10-2 g/l.

Chemical reaction (dissociation) of silver chromate in water: 
Ag₂CrO₄(s) → 2Ag⁺(aq) + CrO₄²⁻(aq).
Ksp(Ag₂CrO₄) = [Ag⁺]²·[CrO₄²⁻].
[CrO₄²⁻] = x.
[Ag⁺] = 2[CrO₄²⁻] = 2x
1,1·10⁻¹² = (2x)² · x = 4x³.

x = ∛1,1·10⁻¹² ÷ 4.

x = 6,5·10⁻⁵ M.

Ksp is the solubility product constant for a solid substance dissolving in an aqueous solution.
[Ag⁺] is equilibrium concentration of silver cations.
[CrO₄²⁻] is equilibrium concentration of chromate anions.

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
