To precipitate Cd²⁺(aq)from solution one could add: A)H₂S(aq) B)HCl(aq) C)HNO₃(aq) D)KI(aq) E)NaCl(aq)

Question

Quizplus · Accepted Answer

The addition of H₂S (sodium sulfide) to a solution containing Cd²⁺ (cadmium cations) would result in precipitation of Cd²⁺ as a solid, since Cd2+ ions have a greater affinity for sulfide ions than sodium ions. HCl (hydrochloric acid) and HNO₃ (nitric acid) would not precipitate Cd²⁺, and KI (potassium iodide) and NaCl (sodium chloride) would not react with Cd²⁺ to produce a precipitate.
