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

	Nature	pH	Solution
(a) (b) (c) (d) (e)	Neutral Strongly alkaline Strongly acidic weakly acidic Weakly alkaline	7 11 1 4 9	D C B A E

Arrangement of the pH in increasing order of hydrogen ion concentration is as follows:

11 < 9 < 7 < 4 < 1
