Science Experiment- Oil of wintergreen

What we attempted: To get the oil to crystalize
Wintergreen oil | Sigma-Aldrich

What happened: the oil just went to a brown color

What should it look like white crystal rocks

What could we change/try: putting less salicylic acid



Steps:
1. Weigh 0.25 grams of salicylic acid into a 10 - 15 cm test tube. This weight does not need to be recorded
2. Add 2.0 mL of methanol to the test tube and swirl until the solid dissolves
3. Slowly add 10 drops of sulfuric acid
4. Place the test tube in a hot water bath and secure by using a utility clamp and heat for 15 minutes
5. Cool the test tube in running water
6. Smell the contents by wafting and record any observations

Disposal
Place all waste and compounds in the appropriately labeled waste bottles in the laboratory

Clean up 
Wash all glassware with soap then rinse 3 times with tap water, and once with deionized water.
