Multiple Choice

What is the net ionic equation for the reaction between nitric acid (HNO3) and calcium hydroxide (Ca(OH)2)?

2H+ + Ca(OH)2 → Ca2+ + 2H2O

Ca2+ + 2NO3- → Ca(NO3)2

Ca(OH)2 + 2HNO3 → Ca(NO3)2 + 2H2O

H+ + OH- → H2O

Verified step by step guidance

Identify the reactants and products in the given chemical equation: Nitric acid (HNO3) and calcium hydroxide (Ca(OH)2) react to form calcium nitrate (Ca(NO3)2) and water (H2O).

Write the balanced molecular equation for the reaction: \( \text{Ca(OH)}_2 + 2\text{HNO}_3 \rightarrow \text{Ca(NO}_3)_2 + 2\text{H}_2\text{O} \).

Break down the molecular equation into its complete ionic form by dissociating all strong electrolytes into their respective ions: \( \text{Ca}^{2+} + 2\text{OH}^- + 2\text{H}^+ + 2\text{NO}_3^- \rightarrow \text{Ca}^{2+} + 2\text{NO}_3^- + 2\text{H}_2\text{O} \).

Identify and cancel out the spectator ions, which are ions that appear on both sides of the equation without undergoing any change. In this case, \( \text{Ca}^{2+} \) and \( \text{NO}_3^- \) are spectator ions.

Write the net ionic equation by including only the ions and molecules that participate in the reaction: \( \text{H}^+ + \text{OH}^- \rightarrow \text{H}_2\text{O} \).
