A solution contains the ions Ag⁺,Pb²⁺,and Ni²⁺.Dilute solutions of NaCl,Na₂SO₄,and Na₂S are available to separate the positive ions from each other.In order to effect separation,the solutions should be added in which order?

Question

Quizplus · Accepted Answer

To separate Ag+, Pb2+, and Ni2+ ions, the correct order of adding solutions is Na2SO4 (to precipitate Pb2+ as PbSO4), followed by NaCl (to precipitate Ag+ as AgCl), and finally Na2S (to precipitate Ni2+ as NiS).

A Solution Contains the Ions Ag+,Pb2+,and Ni2+
