Question

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.

Answer 1

ph-7indicates neutral
ph-1indicates strong acid
ph-4indicates weakly acidic
ph-11indicates strong alkaline
ph-9 indicates weakly alkaline

Answer 2

We have been given 5 solutions with 5 different pH levels and we need to answer a few questions according to the pH levels given to us.

A) Solution D is NEUTRAL

B) Solution C is STRONGLY ALKALINE

C) Solution B is STRONGLY ACIDIC

D) Solution A is WEAKLY ACIDIC

E) Solution E is WEAKLY ALKALINE
