A. Create a solubility curve for NH4Cl by plotting g NH4Cl/100 mL H20 on the y-axis, and crystallization temperature on the x-axis. Make sure to label each axis. On the same graph as the solubility curve for NH4Cl, add the solubility curve for NaCl using the data provided in Data Table 3.
If you hand-draw your graph, scan or photograph it and insert it below. If you are familiar with Microsoft Excel, use the Excel template available under “Additional Information” on Blackboard: type in the values for solubility of NH4Cl and temperatures from Data Table 2 into the left-hand side table in the Excel spreadsheet, which will automatically fill in the data into the chart below it. Then click on the chart, copy it, and paste it below.
I couldn’t figure out how to graph...
