WebJun 19, 2024 · pH is a measure of how acidic/basic water is. The range goes from 0 - 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base. pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water. WebA pH (little p) of 7 only means neutral water at 25°C, but for other temperatures this means a pH above or below 7. ... Let's say, we have a sample of pure water at 50 degrees Celsius, and our goal is to calculate the pH. Pure water is a neutral substance which means the concentration of hydronium ions, H3O+, is equal to the concentration of ...
