Method: Test the solubility of benzyl alcohol (also repeat separately with your unknown) and of phenol in 1 M (or 2 M) sodium hydroxide (use 2 or 3 drops, or a few crystals of the respective compounds and about 1 mL of alkali). Could this test be used to distinguish a phenol from an alcohol? Report: Explain with the aid of an equation.
