Question

Enter the net ionic equation for this reaction. Express your answer as a net ionic equation. Identify all of the phases in your answer. 2HCl(aq)+Ca(OH)2(aq) → 2H2O(l)+CaCl2(aq)

Answer 1

The net ionic equation for the reaction between HCl and Ca(OH)2 is H+(aq) + OH−(aq) → H2O(l), which represents the formation of liquid water from the hydrogen ions and hydroxide ions.

Step-by-step explanation:

The net ionic equation for the reaction between hydrochloric acid (HCl) and calcium hydroxide (Ca(OH)2) is derived by first writing the complete ionic equation and then cancelling out spectator ions. The complete ionic equation for this neutralization reaction is:

H

+

(aq) + Cl

−

(aq) + Ca

2+

(aq) + 2OH

−

(aq) → Ca

2+

(aq) + 2Cl

−

(aq) + 2H

2

O(l)

Identifying and removing the spectator ions, which are the calcium and chloride ions, we obtain the net ionic equation:

H

+

(aq) + OH

−

(aq) → H

2

O(l)

This equation shows the hydrogen ions from the hydrochloric acid reacting with hydroxide ions from calcium hydroxide to form liquid water.
