Chemistry 121 Colligative Properties Lab Demonstration of Selected Calculations from Choice I Determination of Kf for Naphthalene To determine the Kf for naphthalene‚ we need to find the difference in the freezing point of pure naphthalene and the solution of 1‚4-dichlorobenzene in naphthalene. Let’s say that we did this experiment‚ used 1.00 g 1‚4-dichlorobenzene in 10.00 g naphthalene‚ and found that the freezing temperature of pure naphthalene was 78.2°C‚ while that of the solution was 75
