Assuming the compounds to be completely dissociated in aqueous solutio

1.	Assuming the compounds to be completely dissociated in aqueous solution, identify the pair of the soltions which can be expected to be isotonic at the same temperature ?
Answer» `0.01 M " urea and " 0.01 M NaCI` `0.02 " M urea and 0.02 M Na_(2)SO_(4)` `0.03 " M urea and " 0.02 M MgCI_(2)` `0.01 "M surose and " 0.02 M " glucose " Solution :ACCORDING to Van't Hoff equaiton for a dilution soltuion: `PI=iCRT` For isotionic solution, `pi_(1)=pi_(2)` Sincethe two sloutions are at the same temperature, `i_(1)C_(1)RT=i_(2)C_(2)RT` (a) For urea, `i_(1)=1, C_(1)=0.01M` `"For" NaCI, i_(2)=2, C_(2)=0.01M` `1xx0.01xxRT ne2xx0.01xxRT ("Not isotonic") ` (b)`" For" Naci, i_(1)=2,C_(1)-0.02M` For `Na_(2)SO_(4), i_(2)=3, C_(2)=0.01 M` `2xx0.02xxRTnr3xx0.01xxRT` ("Not isotonic")` (c) For NaCI, `i_(1)=2, C_(1)=0.03 M` For `MgCI_(2), i_(2)=3,C_(2)=0.02 M` `2xx0.03 xxRT=3xx002xxRT` (d) For SUCROSE, `i_(1)=1, C_(1)=0.01M` For glucose, `i_(2)=1,C_(2)=0.02M` `1xx0.01xxRT =2xx0.02xxRT` (Not isotonic) is the correct answer.
