Detailed explanation-1: -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.
Detailed explanation-2: -On this scale, a pH value of 7 is neutral, which means it is neither acidic nor basic. A pH value of less than 7 means it is more acidic, and a pH value of more than 7 means it is more basic.
Detailed explanation-3: -Distilled water has a neutral pH of 7. Molecules are made of atoms and are generally considered neutral, meaning they do not have a positive or negative electrical charge. Water is an example of a neutral molecule made of one oxygen and two hydrogen atoms.
