APFIVE Equilibrium Concentration After Precipitation
The solubility product constant, $$K_{sp}$$, for barium sulfate, $$\text{BaSO}_4$$, is $$1.1 \times 10^{-10}$$. A 50.0 mL sample of 0.020 M $$\text{BaCl}_2$$ is mixed with a 50.0 mL sample of 0.030 M $$\text{Na}_2\text{SO}_4$$. What is the concentration of $$\text{Ba}^{2+}$$ ions in the solution once equilibrium is established?
A
1.0 × 10^-2 M
B
2.2 × 10^-8 M
C
3.7 × 10^-6 M
D
1.5 × 10^-2 M
