    Equimolal Soln of NaCl and BaCl2 are prepared in H2O. Freezing point of NaCl is found to be – 2 °C. What freezing point do you expect from BaCl2 soln ?

    i for NaCl = 2 i for BaCl2 = 3

    i for NaCl = 2 i for BaCl2 = 3

    Therefore TF (BaCl2) = 3*2/2 = 3

    TF for BaCl2 = 3 °C TF = – 3 °C.
