50 mL of 10 N H(2)SO(4), 25 mL of 12 N H...

`50 mL` of `10 N H_(2)SO_(4), 25 mL` of `12 N HCI` and `40 mL` of `5N HNO_(3)` are mixed and the volume of the mixture is made 1000 mL by adding water. The normality of resulting solution will be

A

1 N

B

2 N

C

3 N

D

4 N

Text Solution

Verified by Experts

The correct Answer is:
A
`H_(2)SO_(4) ` HCl `HNO_(3)` Total volume
`N_(1)V_(1) + N_(2)V_(2) + N_(3)V_(3) = N xx 1000mL`
`N = ( N_(1)V_(1) + N_(2)V_(2) + N_(3) V_(3))/(1000)`
` = (50 xx 10 + 25 xx 12 + 40 xx 5)/(1000)`
`N = (500 + 30 + 200)/(1000) = (1000)/(1000) = 1N`
