If a solution of 0.46 M Mn2 and 0.46 M Cd2+ is gradually made basic, what will the concentration of Cd2* be when Mn(OH)2 just begins to precipitate? Assume no change in the volume of the solution. For Mn(OH)2, Kp1.6 x 10-13 and for Cd(OH)2, Kp = 7.2 x 10-15; thus, Mn(OH)₂ is soluble than Cd(OH)₂. [Cd²]- i M

If a solution of 0.46 M Mn² and 0.46 M Cd2+ is gradually made basic, what will the concentration of Cd2* be when Mn(OH)2 just begins
to precipitate? Assume no change in the volume of the solution.
For Mn(OH)2. K-1.6 x 10-13 and for Cd(OH)2, Kp = 7.2 x 1015; thus, Mn(OH)₂ is
soluble than Cd(OH)2.
