7.) Ethylene glycol [CH2(OH)CH2(OH)] is a common automobile antifreeze. It is water soluble and
fairly nonvolatile (b.p. 197°C). Calculate (a) the freezing point and (b) the boiling point of a

Expert Solution

Step 1

when a solute is added to a solution there is decrese in vapour pressure on the surface of solution and to freeze that the tempreature must be reduced to a sufficient low so that vapour pressure again become equal to the vapour pressure of corresponding solid phase and hence the substance will freeze
