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.

Text Solution

Verified by Experts

(a) Nuetral -Solution D with pH 7.
(b) Strongly alkaline -Solution C with pH 11
© Strongly acidic -Solution B with pH 1.
(d) Weakly acidic -Solution A with pH 4.
(e) Weakly alkaline -Solution E with pH 9.
The pH can be arranged in the increasing order of the concentration of hydrogen ions as ` 11 lt 9 lt 7 lt 4 lt ` .
