when solutions of nitric acid and sodium hydroxide react, which of the following are present in the net ionic equation? choose all that apply.
a hydrogen ion
b sodium ion
c hydroxide ion
d nitrate ion

Explanation:

Step1: Write the chemical reaction

$HNO_3(aq)+NaOH(aq)
ightarrow NaNO_3(aq) + H_2O(l)$

Step2: Write the complete ionic equation

$H^+(aq)+NO_3^-(aq)+Na^+(aq)+OH^-(aq)
ightarrow Na^+(aq)+NO_3^-(aq)+H_2O(l)$

Step3: Write the net - ionic equation

Cancel out the spectator ions ($Na^+$ and $NO_3^-$). The net - ionic equation is $H^+(aq)+OH^-(aq)
ightarrow H_2O(l)$

Answer:

A. hydrogen ion
C. hydroxide ion
