Why do we use h+ ions to know the pH of a solution, why do we not use oh-? |
| Answer» In common usage, the term hydrogen ion is used to refer to the hydrogen ion present in water solutions, in which it exists as the combined molecule H ·H O.The formula H ·H O is also commonly written as H O and denotes the hydronium or oxonium ion. The amount of hydrogen ion present in a water solution is used as a measure of the acidity of a substance; the higher the concentration of hydrogen ion the more acidic the solution and the lower the pH. | |
