Solubility Equilibria

 

82) Ksp = 2.5 x 10-10          [Ba2+] = 2.0 x 10-8

          

      Ba(MnO4)2(s) Ba2+(aq) + 2MnO4-(aq)

      Ksp = [Ba2+] x [MnO4-]2

      2.5 x 10-10 = 2.0 x 10-8 x [MnO4-]2

      [MnO4-] = 0.11 M

      [KMnO4] = 0.11 mol  MnO4-/L x 1 mol KMnO4/1 mol  MnO4- = 0.11 M
