The `p^(H)` of a 1 lit solution is 2. It is diluted with water till it becomes `4`. How many liters of water is added?

A

`99`

B

`9`

C

`999`

D

`9.9`

Text Solution

Verified by Experts

The correct Answer is:
A
`p^(H) = 2 , (H^(+)) = 10^(-2)`
`10^(-2) xx 1 = 10^(-4) xx V`
`V_(2) = (10^(-2))/(10^(-4)) = 10^(2) = 100`
Use of water `= V_(2) - V_(1)`
`= 100 - 1 = 99`
