Question

Your experiment consists of three stages: Separation, Recovery, and Purification. In the Separation stage, you are physically separating three compounds, a carboxylic acid, a phenol, and a neutral compound. In the procedure, which compound is separated first?

Question 6 options:

neutral

carboxylic acid

phenol

1.

The purpose of RECOVERY is to change the chemical form of the extracted components back to its original molecular form. What reagent is added to recover the carboxylic acid and phenol from the aqueous layer?

Question 3 options:

	ether
	3M sodium hydroxide
	hydrochloric acid
	saturated sodium bicarbonate

If you have a mixture of two compounds, one a neutral organic compound and the other an ionic salt, which layer would each of them be more soluble?

Question 1 options:

	They would both be more soluble in the organic layer
	The organic compound would be more soluble in the aqueous layer and the ionic compound would be more soluble in the organic layer
	The organic compound would be more soluble in the organic layer and the ionic compound would be more soluble in the aqueous layer
	They would both be more soluble in the aqueous layer
