An electric current is passed through two electrolytic cells connected in series one containing aqueous AgNO_(3) solution while the other containing aqueous H_(2)SO_(4). The volume of oxygen that would be liberated at 25^(@)C and 750 mm pressure from H_(2)SO_(4) if 1 mole of Ag^(+) ions are deposited from AgNO_(3) solution.

1.	An electric current is passed through two electrolytic cells connected in series one containing aqueous AgNO_(3) solution while the other containing aqueous H_(2)SO_(4). The volume of oxygen that would be liberated at 25^(@)C and 750 mm pressure from H_(2)SO_(4) if 1 mole of Ag^(+) ions are deposited from AgNO_(3) solution.
Answer» 6.2 L 7.2 L 8.0 L 10.0 L Solution :(a) Since Ag is monovalent , `1" mol Ag" -=1" Eq Ag"-=1" Eq "O_(2)` WEIGHT of `O_(2)` liberated =8 G. `T=298" K", P=(750)/(760) atm` `PV=nRT=(W)/(M)RT` `VO_(2)=(WRT)/(MP)` `=((8G)xx(0.0821" L atm " K^(-1) mol^(-1))xx(298K))/((32" g mol"^(-1))xx(0.987" atm"))=6.2" L"`
