Phenols are less acidic than carboxylic acid
WebRemember - the smaller the number the stronger the acid. Comparing the other two to ethanoic acid, you will see that phenol is very much weaker with a pK a of 10.00, and … WebWhen a carboxylic acid dissolves in a basic solution, the ratio of carboxylate ion to carboxylic acid increases dramatically. Thus, when acetic acid is placed into a solution of sodium bicarbonate at pH 8.5, less than 0.020 of the carboxylic acid remains. Since carboxylate ions have a negative charge, they are more soluble than carboxylic acids.
