Question

question 1. a student has a mixture of ethanol (a type of alcohol) and water, whose properties are described in the table below. substance form at r.t.p. solubility boiling point magnetism ethanol liquid soluble 78°c not magnetic water liquid n/a 100°c not magnetic the student wants to separate the ethanol from the mixture. she decides to use distillation. part a. which of the substances has a higher boiling point? part b. when the mixture is heated up, what will happen? part c. can distillation be used to effectively separate the ethanol from the mixture?

Explanation:

Step1: Identify boiling - point values

From the table, ethanol has a boiling - point of 78°C and water has a boiling - point of 100°C.

Step2: Analyze heating of the mixture

When heated, the substance with the lower boiling - point (ethanol) will vaporize first.

Step3: Evaluate distillation method

Since ethanol and water have different boiling - points, distillation can separate them as the more volatile ethanol will vaporize and be condensed and collected before water starts to boil.

Answer:

Part A: Water
Part B: Ethanol will vaporize first.
Part C: Yes
