If 1 litre aq. Solution of `H_(2)SO_(4)` ( `10%` by weight) with density 1.1 gm/ml, find th `pH` of solution.

A

`-log2.244`

B

`-log1.96`

C

`-log1.86`

D

`-log3.87`

Text Solution

Verified by Experts

The correct Answer is:
A
Let us take `100 gm` solution `implies 10 gm H_(2)SO_(4)` in `90 gm H_(2)O`
`100/1.1 ml` solution `=10/98="mol" H_(2)SO_(4)`
So, `M=(10xx1.1)/(98xx0.1)=110/98=1.122impliesN=2.244`
`pH=-log2.244`
