Five solutions A, B, C, D and E when tested with universal indicator s

1.	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» Solution – pH Value A → 4 B → 1 C → 11 D → 7 E → 9 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 ‘E1 is weakly alkaline ∴ Increasing order of Hydrogen ion concentration : C < E < D < A < B

Answer»

Solution – pH Value

A → 4

B → 1

C → 11

D → 7

E → 9

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 ‘E1 is weakly alkaline

∴ Increasing order of Hydrogen ion concentration :

C < E < D < A < B
