I. Benzoic acid is soluble in diethyl ether but not water; however, benzoic acid
is extracted from diethyl ether with aqueous sodium hydroxide.
1. Complete the acid-base reaction below by writing the products of the reaction and
label the acid, the base, conjugate acid, and conjugate base.
2. Indicate the solubility of benzoic acid and its conjugate base in diethyl ether and in
water.
