ABSTRACT

Experiment entitled “Colligative properties of solution” aims to studying influence of type of solution to the boiling point by finding the influence using two types of solution. The types of solution are electrolyte solution and non-electrolyte solution and each has different mass in 25 ml pure water. We used salt as the electrolyte solution and sugar as the non-electrolyte solution. The result of this experiment was suitable with the hypothesis that the electrolyte solution needs more energy to boil. The conclusion of this experiment is the type of solution will affect the boiling point of the solution itself. Heavier mass of solution will has bigger number of boiling point because the solute substance will block the heat out, so the solution needs more energy to boiling. Electrolyte solution has higher boiling point than non-electrolyte solution, because influenced by Van’t Hoff factor that electrolyte solution has more than 1(one), while non-electrolyte solution always just has 1(one).
