​

Answer 1

Answer:

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

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: (a) neutral -> D

(b) strongly alkaline -> C

(c) strongly acidic -> B

(d) weakly acidic -> A

(e) weakly alkaline -> E

The arrangement of pH in increasing order of hydrogen-ion concentration is 11<9<7<4<1

Explanation:

(i) Neutral (pH = 7), (ii) Strongly acidic (pH = 1), (iii) Strongly alkaline (pH= 11), (iv) Weakly alkaline (pH = 9), (v) Weakly acidic (pH = 4). Please note that higher the pH of solution, lesser will be H+ ion concentration.
