What volume at `STP` of ammonia gas will be required to be passed into `30 mL` of `1N H_(2) SO_(4)` solution to bring down the acid normality to `0.2 N`?

Text Solution

Verified by Experts

Normality is the number of milliequivalents (meq) per mL
`"meq of 0.2 N "H_(2)SO_(4)" in 30 mL "=30xx0.2=6`
`therefore" meq of "H_(2)SO_(4)" required to be beutralized by "NH_(3)=30-6=24`
`"But 1 mole of "NH_(3)="1 g eq, i.e. 1000 meq of "NH_(3)="22400 mL at S.T.P."`
`therefore" 24 meq of "NH_(3)=(22400)/(1000)xx"24 mL = 537.6 mL"`
