Explanation:
Detailed explanation-1: -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.
Detailed explanation-2: -The pH value from 0 to 7 indicates the acidic nature of solution whereas from 7 to 14 indicates the basic nature of solution.
Detailed explanation-3: -A solution of a strong acid, such as hydrochloric acid, at concentration 1 mol dm−3 has a pH of 0.
Detailed explanation-4: -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.
