Explanation:

Calculate the solubility of BaCrO₄ in water at 25°C. You'll find data in the ALEKS Data tab. Round your answer to 3 significant digits.

Step 1: Write the reaction for the solution of BaCrO₄

BaCrO₄(s) ⇄ Ba²⁺(aq) + CrO₄²⁻(aq)

Step 2: Make an ICE chart

We can relate the molar solubity (S) with the solubility product constant (Ksp) using an ICE chart. The Ksp for BaCrO₄ is 1.17 × 10⁻¹⁰.

        BaCrO₄(s) ⇄ Ba²⁺(aq) + CrO₄²⁻(aq)

I                               0                  0

C                             +S               +S

E                               S                 S

The solubility product constant is:

Ksp = 1.17 × 10⁻¹⁰ = [Ba²⁺] [CrO₄²⁻] = S²

S = √1.17 × 10⁻¹⁰ = 1.08 × 10⁻⁵ M
