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. Thus, measure… WebThe pH scale was developed by chemist Soren Sorenson in 1909 as a more convenient way to quickly compare the acidity of different solutions. The pH of a solution is the negative logarithm of its hydronium ion concentration. For example, a solution with 1 × 10 −5 M hydronium concentration has a pH of 5. The greater the hydronium ion ...
