What is the concentration of `NO_(3)^(-)` ion on mixing equal volume solution of 0.1 M `AgNO_(3)` and 0.2 M NaCl ?

A

0.1 M

B

0.15 M

C

0.2 M

D

0.05 M

Text Solution

Verified by Experts

The correct Answer is:
D
`0.1 M AgNO_(3)` and 0.2 M NaCl are mixed
So total volume = 2 litre
So concentration will be halved.
`therefore` Concentration of `AgNO_(3)=(0.1)/(2)=0.05 M`
