gpt
An acid is a substance that produces hydrogen ions (H+) when it dissolves in water, and a base is a substance that produces hydroxide ions (OH-) when it dissolves in water.
Explanation: The concept applies to aqueous solutions but has limitations as it only considers OH- bases and was later improved upon by Bronsted and Lowry.
