How Do You Write An Equation For Acetic Acid Plus Water?

An acid is a chemical substance which gives protons in its solution. The molecular formula for acetic acid is CH₃COOH. Acetic acid is colorless organic compound and also known as ethanoic acid. Acetic acid is a weak acid and when dissolve in water gives a proton or hydrogen ion.

CH₃COOH ------> CH3COO^-1 + H⁺¹

The equation for the reaction is;

CH₃COOH + H₂O ------> CH₃COO^-1 + H₃O⁺¹

When acetic acid is added to water, acetate ion CH₃COO^-1 and hydronium ion H₃O⁺¹ are formed.
