Question

1.
Five solutions A, B, C, D and E when tested with universal indicator showed
pH as 5,2,1,3,7 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. (AS1) (T.Q)​

Answer 1

Answer:

please note that the ph are 6 and you have written only five solutions so, i have added one F solution

Explanation:

A- weakly acidic

B- Highly acidic

C- highly acidic

D- highly acidic

E- neutral

F- weakly alkaline

ph according to increasing hydrogen ion concentration-

9, 7, 5, 3, 2, 1
