Explanation:
Detailed explanation-1: -pHs less than 7 are acidic while pHs greater than 7 are alkaline (basic).
Detailed explanation-2: -a solution with a ph of five would tell us that it is alkali neutral or acidic.
Detailed explanation-3: -[H+]=10-7, which we call a pH of 7. In the same way, a solution with a pH of 5 contains 10-5mol/l of hydrogen ions, a solution with a pH of 6 contains 10-6mol/l of hydrogen ions, while the solution with a pH of 7 contains 10-7mol/l of hydrogen ions.
