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

Answer» Solution :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"` |
