A student has a mixture of isopropanol and water. Table 1 gives some physical properties of isopropanol.
Table 1
Melting point of isopropanol -89 degrees
Boiling point of isopropanol 80.3 degrees
Solubility of isopropanol in water is high
1) Name the method that the student should use to separate the mixture to collect pure samples of each substance.
2) Explain how to separate the substances using the method given in 1).
3) Ethanol has a boiling point of 78.4 degrees and a melting point of -114.7 degrees.
Suggest why this method could not be used to separate a mixture of isopropanol and ethanol.
I can't quite get the question. Are you asking to separate isopropyl alcohol and water? If so you can't do it by fractional distillation. Freezing it is better way. You can use your text/notes to describe that procedure.
We have not learned about freezing. I do not this is the procedure to choose.
Question 1 says a mixture of isopropanol and water and question 3 says a mixture of isopropanol and ethanol which are both different. What method can be used for question 1 but not for question 3 and what is the reason?
Please help with the questions. This question I posted is like one question with different parts.
