Answer:

E) II and III.

Explanation:

Let's consider the complete ionic equation when solutions of acetic acid and sodium hydroxide react. It includes all the ions and molecular species.

CH₃COO⁻(aq) + H⁺(aq) + Na⁺(aq) + OH⁻(aq) ⇒ CH₃COO⁻(aq) + Na⁺(aq) + H₂O(l)

The net ionic equation includes only the ions that participate in the reaction and the molecular species.

H⁺(aq) + OH⁻(aq) ⇒ H₂O(l)

The species not present are:

II. acetate ion

III. sodium ion
