Five solutions A,B,C,D and E when tested universal indicator showed pH

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