Five solutions A,B,C,D and E when tested with 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.
(a) Solution D is neutral having pH 7
(b) Solution C is strong alkaline with pH 11
(c) Solution B is strong acidic with pH 1
(d) Solution A is weak acidic with pH 4
(e) Solution E is weak alkaline with pH 9
11 < 9 < 7 < 4 < 1. The pH can be arranged in the increasing order of the concentration of hydrogen ions.
