Pour one tablespoon (15 mL) of water into one container, and pour onetablespoon (15 mL) of rubbing alcohol into another container.2. Carefully move the containers around until you don't know which is which. Then, pick one to use and labelit unknown. (Or, have someone else pick the unknown container for you.) Pour the contents of the othercontainer into the sink, and rinse and dry the container for reuse.3. For now, set aside the container with the unknown substance.4. Label the two empty containers water and alcohol. Pour one tablespoon (15 mL) of water into thecontainer labeled water, and pour one tablespoon (15 mL) of alcohol into the container labeled alcohol.Note that you now have three containers labeled unknown, water, and alcohol.Part AWater and rubbing alcohol have distinct properties and will react differently with the same substance.Observe these properties of water and rubbing alcohol: color, smell, and ability to dissolve salt.
