Problem 1PE
Calculation of Boiling-Point Elevation and Freezing-Point Depression
Automotive antifreeze contains ethylene glycol, CH2(OH)CH2(OH), a nonvolatile nonelectrolyte, in water. Calculate the boiling point and freezing point of a 25.0% by mass solution of ethylene glycol in water.
Which aqueous solution will have the lowest freezing point? (a) 0.050 m CaCI2, (b) 0.15 m NaCI, (c) 0.10 m HCI, (d) 0.050 m CH3COOH. (e) 0.20 m C12H22Q11.
