Question 3 1 pts How does an acid/base extraction separate two compounds in a mixture with similar solubilities? • The added acid or base changes the polarity of the aqueous layer, thus allowing for separation of compounds. • The added acid or base performs a chemical reaction with one of the compounds to make a new species with different solubility, thus allowing for separation. • The added acid or base performs a chemical reaction with one of the compounds to make a new species that precipitates out of solution, leaving the other compound behind. • The added acid or base makes a third layer, allowing for easier transfer between the aqueous and organic layers.
