Nickel metal is plated as an underplating on steel surfaces that are to be chrome or gold plated. The nickel metal in a rinse bath following the nickel plating process is found to contain both nickel ion (Ni2+) and calcium ion (Ca2+) at 0.02 M. A) Can the concentration of nickel ion be reduced to 1.0 x 10-5 M by precipitation of the nickel ion as nickel hydroxide without precipitating the calcium ion as calcium hydroxide? The Ksp of calcium hydroxide is 6.5x10-6 and the Ksp of nickel(II) hydroxide is 6x10-13
