Date: 2/19/10 Due Date: 2/26/10 II. Objective The goal of this lab was to determine the amount of impurity‚ in the form of oil‚ in water using the method of solvent extraction‚ also known as liquid-liquid extraction‚ a method of separating two materials with different physical and/or chemical properties. Two methods of evaporation will be used to finally determine the concentration of impurity- one using an explosion-proof hot-plate‚ and one using a rotovap. III. Theory Fig. 1a+1b. Figure
