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: -A solution of a strong acid, such as hydrochloric acid, at concentration 1 mol dm−3 has a pH of 0.
Detailed explanation-3: -Any solution that has a pH of less than 7 is considered acidic, and anything above a pH of 7 is basic.
Detailed explanation-4: -As you can see from the pH scale above, pure water has a pH value of 7. This value is considered neutral-neither acidic or basic.
Detailed explanation-5: -A solution with a pH of less than 7 is acidic, while one with a pH of greater than 7 is basic, or alkaline.
