Excess solid barium sulfate, BaSO4(s)\text{BaSO}_4(s), is mixed with pure water at 25∘C25^\circ\text{C} until equilibrium is established. For BaSO4(s)⇌Ba2+(aq)+SO42−(aq)\text{BaSO}_4(s)\rightleftharpoons \text{Ba}^{2+}(aq)+\text{SO}_4^{2-}(aq), Ksp=1.0×10−10K_{sp}=1.0\times10^{-10}. What is the equilibrium concentration of Ba2+\text{Ba}^{2+} in the saturated solution?
