Hi guys, I've got the following question that I could use some help with:
You have two solutions, A and B.
Solution A contains a mixture of water and Glycerol (V\V % is 1:1)
Solution B contains a mixture of Ethanol and water (V\V % is 1:1)
Data: Glycerin - Boiling point at 290°C, freezing point at 18.6°C, Molar mass 92 g/mol
Ethanol - Boiling point at 78°C, freezing point at -114°C, Molar mass 46 g/mol
Water - Boiling point at 100°C, freezing point at 0°C, Molar mass 18 g/mol
Determine whether the following is true or false:
1. The B.P of B is higher than that of water.
2. The B.P of A is higher than that of water.
3. The F.P of B is lower than that of water.
4. The F.P of A is lower than that of water.
To me it would seem all but 1 is true. 4 is problematic as I know glycerin is used as an antifreeze, yet it doesn't seem to make sense. Help?
