Question

why does adding ethanol to water change its freezing point?

Answer 1

Answer:

Water molecules are more attracted to each other than ethanol (alcohol) molecules, because water has more hydrogen atoms bonded to oxygen. ... So, that's why alcohol has a much lower freezing point – -114.7 degrees Celsius (-174.6 degrees Fahrenheit), as opposed to water's freezing point of 0 degrees C (32 degrees F.)

Explanation:

Answer 2

Answer:

Since ethanol molecules aren’t as sticky as water molecules, the temperature has to be a lot lower before the forces of attraction overcome the energy of motion and fix the molecules into their array sites. So, that’s why alcohol has a much lower freezing point – -114.7 degrees Celsius (-174.6 degrees Fahrenheit), as opposed to water’s freezing point of 0 degrees C (32 degrees F.)
