Identify a spectator ion in the following acid-base reaction.
Ca(CO₃) (s) + 2HCl(aq) $\rightarrow$ CaCl₂(aq) + 2H₂O(l ) + CO₂(g)

Question

Identify a spectator ion in the following acid-base reaction. Ca(CO₃)(s) + 2HCl(aq) $\rightarrow$CaCl₂(aq) + 2H₂O(l ) + CO₂(g)

Quizplus · Accepted Answer

In the reaction, Ca(CO₃) and HCl react to form CaCl₂ and CO₂(g). The only spectator ion present in the reaction is Cl^- since it does not participate in the reaction and remains unchanged on both sides. Therefore, the correct answer is C) Cl^-.
