Webb9 apr. 2024 · Generally, acids are substances with a pH value of less than 7.0. The value goes on decreasing as the amount of H+ ion increases in the solution. Strong acids are the substances that release H+ ions rapidly or that are 100% ionizable in the solution. Thus, the strong acids have less pH value, nearly 0 to 1. Pure water is neutral. When an acid is dissolved in water, the pH will be less than 7 (25 °C). When a base, or specifically an alkali, is dissolved in water, the pH will be greater than 7. A solution of a strong acid, such as hydrochloric acid, at concentration 1 mol dm has a pH of 0. A solution of a strong alkali, such as sodium hydroxide, at concentration 1 mol dm , has a pH of 14.
