You performed an experiment in which you measured the freezing point of pure cyclohexane and the freezing point of 8.60 grams of cyclohexane with 0.253 grams of an unknown solute. The Kf for cyclohexane is -20.5

Chemicals should never be returned to the original container unless instructed to do so by the professor.

Provide an explanation on how adding soap to water helps to emulsify oils and fatty substances?

All chemicals used in the chemistry lab can be discarded down the sink and must be done so when the experiment is over.

Your laboratory has a fire blanket, eyewash fountain, safety shower and a first aid kit.

It is good laboratory protocol to inform other students if they are not following good laboratory practices. If they continue, then you should “rat” on them to the instructor.
