Hydrolic acid solution A and B have concentration of 0.5 N and 0.1N respectively. The volume of solutions A and B required to make 2 litres of 0.2 N hydrochloric are

A

(a)`0.5 L of A+1.5L of B`

B

(b)`1.5 L of A+0.5L of B`

C

(c )`1.0 L of A+1.0L of B`

D

(d)`0.75 L of A+1.25L of B`

Text Solution

Verified by Experts

The correct Answer is:
A
`NV=N_(1)V_(1)+N_(2)V_(2)`
`0.2xx2=0.5x+0.1(2-x)`
`0.4=0.5x=0.2-0.1x`
`0.0=0.4x`
`x=1/2L=0.5L`
