Answer:
Ca²⁺ and Cl⁻
Explanation:
In a chemical reaction, spectator ions are ions that <em>are not involved in the reaction</em>, that means are the same before and after the reaction.
In water, calcium hydroxide, Ca(OH)₂ is dissociated in Ca²⁺ and OH⁻. Also, hydrochloric acid, HCl, dissociates in H⁺ and Cl⁻. The reaction is:
Ca²⁺ + 2OH⁻ + 2H⁺ + 2Cl⁻ → 2H₂O + Ca²⁺ + 2Cl⁻
<em>The ions that react are H⁺ and OH⁻ (Acid and base producing water)</em>
<em />
And the ions that are not reacting, <em>spectator ions</em>, are:
<h3>Ca²⁺ and Cl⁻</h3>
