An Exercise in Freezing Point Depression

2. Prepare a plot of ∆T vs. m. Include trials 0 through 3. Use Excel or the graph paperat the back of the Manual. Each part (a, b, and c below) must be entirely correct toreceive credit for that part.a) Put your name on the graph, provide a title, and label the axes.b) Plot the 4 data points and draw the “best” straight line.c) Calculate the slope of your line, ∆T = imK fd) Calculate “i” from this slope. (Slope = iK f)e) What is the theoretical value of "i" for NH 4Cl? How does your value compareto the theoretical value of “i” for NH 4Cl?f) Use the experimental value of “i” to determine the “colligative molality, i x m,where m is the calculated molality of the compound (not of the ions.)10-14
