Solution

We know that solutions that have pH values less than 7 (from 0) are acidic, those with pH greater than 7 (up to 14) are basic (or alkaline) and those with pH 7 are neutral. The lower the pH, the higher the acidity, and the higher the pH, the higher the basicity. Let us classify solutions with the given pH values as acidic, alkaline or neutral.
 

The pH of the solution Nature of the solution
(i) 9 Basic
(ii) 4 Acidic
(iii) 7 Neutral
(iv) 1 Acidic
(v) 10 Basic
(vi) 3 Acidic
