Understanding the Answer
Let's break down why this is correct
Answer
In a solution, a substance that donates hydrogen ions is called an acid. An acid gives away H⁺ ions when it dissolves in water, so the water becomes more acidic. For example, when hydrochloric acid (HCl) dissolves, it releases H⁺ ions that make the solution acidic. This property is what defines an acid in the acid‑base classification.
Detailed Explanation
An acid is a substance that can give away hydrogen ions (H+). Other options are incorrect because A base does not give hydrogen ions; it takes them; Neutral means the solution has a pH of 7, not that it donates ions.
