Steam distillation is used to purify a compound which is steam volatil

1.	Steam distillation is used to purify a compound which is steam volatile and insoluble in water. The impurities should not be steam volatile. It is based on the principle that liquid will boil when partial sure. p=p_(1)+p_(2). It reduces the boiling point of liquid.("Weight of water distilled")/("Wt of substance distilled")=("M.wt of water"xx"V.P. of steam")/("M.Wt of substance"xx "V.P. of aniline")Calculate weight of aniline distilled if weight of water distilled is 100g when P_("organic compound")=100mm and P_(H_(2)O)=200mm
Answer» <P>250 G 258 g 100 g 25.8 g SOLUTION :`(omega_(1))/(omega_(2))=(P_(1).18)/(P_(2).93)` suffix 1 for `H_(2)O` , suffix 2 for ANILINE, MW of aniline = 93. `(100)/(omega_(2))=(200xx18)/(100xx93)rArr omega_(2)=258.33`
