How many times a 0.1 M strong monobasic solution should be diluted so that the pH of the resulting solution is tripled ?

A

50

B

10

C

25

D

100

Text Solution

Verified by Experts

The correct Answer is:
D
`pH = -log [H^(+)] `
pH of 0.1 M strong monobasic acidic solution = 1
pH of the resulting solution = 3
` :. [H^(+)] = 10^(-3) = (0.1)/100`
So , the original solution is diluted 100 times .
