Answer:
1.08 × 10⁻⁵ M
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
