0.28. Five solutions A, B, C, D and when tested with universal indicator showed pH as 4,111,7 and respectively
Which solution is
neutral?
(b) strongly alkaline? (c) strongly acidict (d) weakly acidi
(e) weakly alkaline?
Arrange the pH in increasing order of hydrogen-ion concentration
Ans. Solutions
A B C D E
11 7
(a) Dis neutral (pH-7)
the neutral pH
(b) C is highly alkaline (pH = 11) the highest pH
(c) B is strongly acidic (pH =1)
the lowest pH
(d) A is weakly acidic (pH = 4)
(e) Eis weakly alkaline (pH9)
The arrangement of pH in the increasing order of hydrogen ion concentration is 11 97.4.1
