Suppose you wanted to cause Pb2+ ions to come out of solution as solid Pb. What metal could you use to accomplish this?
Solution 80P :
To separate Pb metal solid from the solution containing Pb2+ ions, we need to add a metal that is higher than Pb on the activity series and the one which will not significantly react with water.
Zinc(Zn), Manganese(Mn), Iron(Fe), Chromium(Cr), Aluminium(Al), Magnesium(Mg), Sodium(Na), Calcium(Ca), Potassium(K), Lithium(Li), Nickel(Ni) or tin (Sn) are the metals that could be added to separate Pb from the solution containing Pb2+ ions.
