I read a presentation about this experiment.
Hypothesis: If I add salt to water, then it will take longer for the water to freeze.
The given variables were:
Controlled Variables:
1. Refrigerator
2. type of cups used (contains water and varying amount of salt)
Independent Variable
1. Amount of Salt
Dependent Variable
1. Amount of frozen water
Conclusion: Water with salt take longer to freeze.
<u>Answer:</u>
The freezing point of a 1.7 mole aqueous ethylene glycol solution is 3.2°C
<u>Explanation:</u>
Moles present in aqueous ethylene glycol solution= m=1.7
Depression constant for water = = 1.8 deg C/m
According to formula
=1.8* 1.7
=3.2
Hence the freezing point of aqueous ethylene glycol solution is 3.2°C
Answer:
