Explanation:
Detailed explanation-1: -pH is a measure of how acidic/basic water is. The range goes from 0 to 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.
Detailed explanation-2: -pH is a logarithmic measure of the hydrogen ion concentration of an aqueous solution pH =-log[H+] where log is the base 10 logarithm and [H+] is the hydrogen ion concentration in moles per liter. pH describes how acidic or basic an aqueous solution is, where a pH below 7 is acidic and a pH greater than 7 is basic.
Detailed explanation-3: -Pure water is neither acidic or basic; it is neutral.
