- In a test tube, dissolve 10 drops of methanol in 3 ml. of water. Oxidize a copper wire spiral by passing it through a Bunsen burner. Plunge the red-hot wire into the alcohol solution several times, cooling the solution under the tap (faucet) so as not to evaporate too much of it. Next, add 1 drop of 0.5% resorcinol solution. Measure 2 ml. of concentrated sulfuric acid (CAUTION!) and pour this carefully down the sides of the test tube containing the mixture. Note the color of the zone intermediate between the acid and the solution.
