Available are `1L` of `0.1M NaCl` and `2L` of `0.2M CaCl_(2)` solutions. Using only these two solutions what maximum volume of a solution can be prepared having `[Cl^(-)]=0.34M` exactly. Both electrolytes are strong

A

`2.5L`

B

`2.4L`

C

`2.3L`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
A
Let volumes takne by `'x' & 'y'` litres, so (0.1x+0.4y)/(x+y)=0.34 & V_(g)=(x+y)` (to be maximised)
so `y=4x` so for maximum volome
`y=2L & x=(1)/(2)L`
