Give the spectator ions for the reaction that occurs when aqueous solutions of Na₂CO₃ and HCl are mixed. A) H⁺ and CO₃^2- B) Na⁺ and CO₃^2- C) H⁺ and Cl^- D) Na⁺ and Cl^- E) No spectator ions are present.

Question

Quizplus · Accepted Answer

The balanced equation for the reaction is: Na2S + HCl → 2NaCl + H2S In aqueous solution, Na2S dissociates into Na+ and S2- ions, while HCl dissociates into H+ and Cl- ions. Therefore, the spectator ions are Na+ and Cl-. The correct choice is D - Na⁺ and Cl^-.
