Devise your own distillation set-up. Explain the purpose of each part and the
processes it undergoes.
Given two glasses of water, how will you know if one glass has sugar in it while
the other does not? What if it contains harmful chemicals?
Can you tell which is which among the solutions of saline, syrup, benzoic acid?
How?
Measuring the temperature of a boiling solution is the ultimate recourse in
determining its purity. Why?
Explain how to determine the purity of solution by observing changes in its
temperature until reaching boiling point. Compare each set-up with the
recorded temperature every minute.
