Question 1.
What is differential extraction?
Show hintHide hint
Think about solubility differences.
Question 2.
Why is it necessary to use an organic solvent?
Show hintHide hint
Consider the compatibility of the solvent with the solute.
3Question 3.
What is differential extraction primarily used for?
- To purify solid compounds
- To separate organic compounds from aqueous solutions
- To crystallize chemicals
Show hintHide hint
Think about what 'extraction' means in chemistry.
4Question 4.
True or False: In differential extraction, the organic solvent must be miscible with water.
- True
- False
Show hintHide hint
Consider the definition of 'immiscible'.
Question 5.
A chemist is trying to separate a new compound from an aqueous solution that shows moderate solubility in both water and organic solvents. Describe how they could optimize the extraction process.
Show hintHide hint
Think about how repeated processes can enhance yield.
Question 6.
Discuss the advantages and disadvantages of differential extraction compared to distillation for purifying organic compounds.
Show hintHide hint
Compare the methods based on their principles of separation.
