4) Tert-butanol is an alcohol. Would the addition of another alcohol as the impurity have affected the freezing point and boiling point of tert-butanol? a) Yes, because colligative properties depend on the number of impurity particles and NOT on their chemical properties b) No, because colligative properties depend on the chemical properties of the impurity and NOT on the amount of particles c) Only if the same amounts of the alcohol impurity and tert-butanol are mixed
