What is a solution that has an excess of H (hydrogen) ions?

A solution with an excess of H⁺ ions is known as an acidic solution. Common examples include hydrochloric acid (HCl) and sulfuric acid (H₂SO₄), where the concentration of H⁺ ions is greater than that of hydroxide ions (OH⁻). This excess of hydrogen ions results in a pH value below 7, indicating acidity.
