1.	Five solution A, B, C, D and E when tested with universal indicator showd pH as 4, 1, 11, 7 and 9 respectively. Which solution is (a) neutral ? (b) stongly alkaline ? (c ) strongly acidic ? (d) weakly acidic ? (e) weakly alkaline ? Arrange the pH in increasing order of hydrogen ion concentration.
Answer» SOLUTION :(a) D (B) C (c) B (d ) A (E ) E `C (10-11M) LT E (10-9M) lt D (10-7 M) lt A (10-4 M) lt B (10-1 M)`
