What volume of 0.1 M H(2)SO(4) is requir...

What volume of `0.1 M H_(2)SO_(4)` is required in litres to neutralize completely 1 litre of a solution containing 20 g of NaOH ?

A

`5.0`

B

`0.5`

C

`2.5`

D

`10.0`

Text Solution

Verified by Experts

The correct Answer is:
C
`M_(NaOH)=(W_(B)xx1000)/(m_(B)xxV)=(20xx1000)/(40xx1000)=0.5`
Reaction : `H_(2)O+2NaOH to Na_(2)SO_(4)+2H_(2)O`
`(M_(1)V_(1))/(1)=(M_(2)V_(2))/(2)`
`0.1xxV_(1)=(0.5xx1)/(2)`
`V_(1)=2.5 L`
