Calculate the freezing point depression expected for 0.071m aqueoussolution of Na2SO4. If this solution actually freezes at -0.3200C, what wouldbe the value of Van't Hoff factor?(K for water= 1.860C mol-1 kg)3 |

Answer» Here,m = 0.0711Kf= 1.86∆Tf= 0.320Therefore,∆Tf=i×Kf×mOr, 0.320= i × 1.86 × 0.0711Or, i = 2.42Therefore the Van`t Hoff factor is 2.42 |
