Question
Chapter 5.3, Problem 21E
Interpretation Introduction
Interpretation:
The reason due to which anhydrous sodium sulfate is added to the organic solution extracted from 6M HCl and 6M NaOH needs to be explained.
Concept Introduction :
Extraction is defined as a method used to isolate a substance which is mixed with some other substance. It is done by adding a solvent in which one the substance which needs to be extracted is soluble and other substance is insoluble.

How to separate phenol from a mixture of benzoic acid and phenol by extraction?
Benzoic acid and water were added to the test tube labeled "b.a." After stirring the
mixture, sodium hydroxide (NaOH) vas added until the solid disappeared. Finally,
hydrochloric acid was added drop by drop until blue litmus paper turned red. The
solid present in the test tube after the addition of HCI is most likely:
benzoic acid
benzyl acetate
O benzyl chloride
sodium benzoate

When an acid is neutralized by a base in the presence of phenolphthalein, a faint purple-pink color is observed at the end point; however, after a few minutes, the solution becomes colorless. a. What can you say about the solution when it has a faint purple-pink color? What must have changed about the solution for the color to go away? Assume that the phenolphthalein is still present. b. The cause of the change is the carbon dioxide that is in the air.
