Acetic acid reacts with sodium hydroxide to give sodium acetate and water.
Acetic acid is a weak acid, and thus it is written in molecular form in the net ionic equation.
Water is mainly in molecular form.
Sodium hydroxide and sodium acetate completely ionize in water, and thus they are written in ionic form.
The net ionic equation is :
CH₃COOH(aq) + OH⁻(aq) → CH₃COO⁻(aq) + H₂O(l)
Acetic acid, hydroxide ion, acetate ion and water are present in the net ionic equation.
...... The answer is c.
