Ca(CO₃) (s) 2HCl(aq) CaCl₂(aq) 2H₂O(l ) CO₂(g)

Question

Identify a spectator ion in the following acid-base reaction. Ca(CO₃)(s) 2HCl(aq) CaCl₂(aq) 2H₂O(l ) CO₂(g) A)H⁺ B)Ca²⁺ C)Cl^- D)CO₃^2- E)H₃O⁺

Quizplus · Accepted Answer

The spectator ion is the Cl- ion, which does not participate in the chemical reaction and remains unchanged. In this reaction, Ca2+ and Cl- ions combine to form CaCl2, while the other ions (HSO4-, CO32-, and H+) participate in forming the other products.
