Five solutions A, B, C, D and E showed pH as 4, 7, 1, 11 and 9 respect

1.	Five solutions A, B, C, D and E showed pH as 4, 7, 1, 11 and 9 respectively when tested with universal indicator. Which solution is (i) Neutral (ii) Strongly alkaline(iii) Strongly acidic (iv) Weakly acidic and (v) Weakly alkaline ? Arrange the pH in increasing order of hydrogen ion concentration.
Answer» Solution :(i) Solution B is NEUTRAL. (ii) Solution D is STRONGLY alkaline. (iii) Solution C is strongly acidic. (IV) Solution A is weakly acidic. (v) Solution E is weakly alkaline. Increasing order of hydrogen ion concentration : D, E, B, A and C.
