The ph of pure water

WebbPure water has a pH of 7 at 25°C, meaning it is neutral. When an acid is dissolved in water, the pH will be less than 7, while a base , or alkali , will have a pH greater than 7. A strong acid, such as hydrochloric acid , at concentration 1 mol dm −3 has a pH of 0, while a strong alkali like sodium hydroxide , at the same concentration, has a pH of 14. WebbThe pH of pure water is 7 which means pure water is neutral. Neutral solution: The solution in which the concentration of hydroxide ions equals the concentration of hydrogen ions is a neutral solution. The pH of such a solution is always 7. These solutions are neither acidic in nature nor basic in nature.
