Where does water fall on the pH scale?

Despite what has been written by others (and a common belief) pH is not an arbitrary scale. The fact that degassed pure water at around room temperature has (by chance) an ionic product of 1.0 x 10^-14 means that the activity of H+ ions is 1. read more

Answer Wiki. Despite what has been written by others (and a common belief) pH is not an arbitrary scale. The fact that degassed pure water at around room temperature has (by chance) an ionic product of 1.0 x 10^-14 means that the activity of H+ ions is 1.0 x 10^-7, and the activity of OH- ions is the same. read more

The pH scale is used to measure the alkalinity or acidity of a substance like water. The scale goes from 0 to 14. A pH under 7 indicates that what you’re measuring is acidic, and anything over 7 is alkaline. read more

Acids are lower, bases are higher on the pH scale. When determining the pH of a strong acid or base you should be given a concentration in molarity (moles/liter). read more
