Arrange the following aqueous solutions in order of increasing freezing points (lowest to highest temperature): 0.10 m glucose, 0.10 m BaCl2, 0.20 m NaCl, and 0.20 m Na2SO4.

  • chemistry -

    delta T = i*Kf*molality
    i = 1 for glucose
    i = 3 for BaCl2
    i = 2 for NaCl
    i = 3 for Na2SO4
    You CAN calculate each with the data given and arrange them from the answers OR you can look at i*m and see which is the largest. The largest value of i*m will have the lowest freezing point (the largest delta T) and the smallest value of i*m will have the highest freezing point (smallest delta T).

    What is the boiling point of a solution made by mixing 115 g NaCl in 1 kg of water? (Kb for water is 0.512 C/m)

  • chemistry -

    Arrange the following aqueous solutions in order of decreasing freezing points (lowest to highest temperature): 0.10 m Na3PO4, 0.35 m NaCl, 0.20 m MgCl, 0.15 m C6H12O6 and 0.15 m CH3COOH.
