5 mL of N HCl, 20 mL of N/2 `H_(2)SO_(4)` and 30 mL of `N/3HNO_(3)` are mixed together and volume made to 1L. The normality of resulting solution is

A

0.45

B

0.025

C

0.9

D

0.05

Text Solution

Verified by Experts

Normally equtaion is
`N_(1)V_(1)+N_(2)V_(2)+N_(3)V_(3)=N_(4)(V_(1)+V_(2)+V_(3))`
or `1xx5+20xx(1)/(2)+30xx(1)/(3)=N_(4)(5+20+30)`
`(HCI) (H_(2)SO_(4)) (HNO_(3))`
`therefore` Resulting normality `(N_(4))=(25)/(55)=0.45N`.
