One litre of a solution contains 18.9 gm of `HNO_(3)` and one lire of another solution contains 3.2 gm of NaOH. In what volume ratio must these solutions be mixed to obtain a neutral solution?

A

`3:8`

B

`8:3`

C

`15:4`

D

`4:15`

Text Solution

Verified by Experts

The correct Answer is:
D
For neutral solution, eq. `HNO_(3)` = eq. NaOH
`(((18.9)/(63)))/(1)xxV_(a)=(((3.2)/(40)))/(1)xxV_(b)`
`(V_(a))/(V_(b))=(4)/(5)xx(1)/(3)=(4)/(15)`
