Question

1 a Draw and label the apparatus you could use to separate
a mixture of ethanol and water.
[2 marks]
b What is this method of separation called?
[1 mark)
2 Explain why you would be able to collect a more
concentrated sample of ethanol from a mixture of water
and ethanol using the apparatus drawn in question 1 than
by using simple distillation.
[4 marks)
3 a Describe a method to separate the dyes in coloured inks. (4 marks]
b A paper chromatogram from a mixture of two substances,
A and B, was obtained using a solvent of propanone. Substance B
was found to travel further up the paper than substance A.
What does this tell you about substances A and B. [1 mark]
4 Look at the boiling points of the three liquids in the table:
Liquid
Boiling point in °C
water
100
ethanol
78
propanol
97
A mixture was made by stirring together equal volumes of
these three miscible liquids.
Evaluate the effectiveness of fractional distillation as a way
of separating this mixture into the three pure liquids (B marks]. plz answer in full form with explanation and examples plz and ans completely and fast its for test as a long question. ​

Answer 1

Answer:

1b. it is called Distillation

Explanation:

Distillation is the method used to separate a mixture of miscible liquids whose boiling points are close to each other.

Answer 2

Answer:

1a. see Attachment

2. At 78°C/the boiling point of ethanol, much of the water vapour rising up the fractionating column would condense and return to the heated flask instead of entering the condenser to be collected with the ethanol.
