Graphing Calculator Predicting Solubility from Tabular
Chapter , Problem 73(choose chapter or problem)
Graphing Calculator Predicting Solubility from Tabular Data The graphing calculator can run a program that graphs solubility data. Given solubility measurements for KCl, you will use the data to predict its solubility at various temperatures. Go to Appendix C. If you are using a TI-83 Plus, you can download the program and data sets and run the application as directed. Press the APPS key on your calculator, then choose the application CHEMAPPS. Press 3, then highlight ALL on the screen, press 1, then highlight LOAD and press 2 to load the data into your calculator. Press the keys 2nd and then QUIT, and then run the program SOLUBIL. For L1, press 2nd and LIST, and choose TMP21. For L2, press 2nd and LIST and choose SOL21. If you are using another calculator, your teacher will provide you with keystrokes and data sets to use. a. At what temperature would you expect the solubility to be 48.9 g per 100 g H2O? b. At what temperature would you expect the solubility to be 35 g per 100 g H2O? c. What would you expect the solubility to be at a temperature of 100C?
