Question 1

How do we separate a Mixture into a Pure Substance?

Answer 1

We use physical methods.

Question 2

How do we separate a Compound into an Element?

Answer 2

We use chemical methods.

Question 3

What are the five methods of separating mixtures?

Answer 3

1. Filtration
2. Distillation
3. Evaporation
4. Extraction
5. Chromatography

Question 4

What is Chromatography? Give an example.

Answer 4

Separation is based on different strengths of absorption forces.
(ex. Different food colors dissolve differently In the same solvent due to their chemical differences)

Question 5

What is Evaporation? Give an example.

Answer 5

Separation is based on the ability of a substance to dissolve in a solvent.
(ex. Making Tea!- solid dissolves into a liquid)
