None-the-less, use the program at your own risk, and understand that answers are only as good as the data that you enter. The program has worked perfectly for my AP students during the 2001 year. The program then solves for pH, pOH, Ka, Kb,, , or /. You choose between problems focused on pH and Ka, or pOH and Kb. In addition, the Charles, Boyles, and Combined laws will solve for either original (V 1, P 1, T 1) or new (V 2, P 2, T 2) conditions.īUFFERS solves the various permutations of the Henderson Hasselbalch equation. The ideal gas law can now solve for Molecular weight of an unknown gas. Changes made include asking the user to choose whether you are using atmospheres or kilopascals, and then the allowing the program to solve for the correct variation of the gas constant, R. I greatly appreciate their original work, which helped me in organizing my thoughts and formulas. The work is a modification of programming already done by Bisun and Mad Melvin, as posted at the Ti.calc ftp site. GASLAWS is designed to solve Charles Law, Boyle's Law, The Combined Law, and The Ideal Gas Law. For instance, in the conversion of Al3+ ion to elemental aluminum, you would enter "3" as the ionic charge (without the quotes!) Gas Laws When the program asks for the ionic charge of the metal, you must enter the number of electrons that are gained by the metal when it is reduced at the cathode. It is capable of calculating time required for plating, amperes required for plating, moles of electrons transferred, moles of metal plated, grams of metal plated, and molar mass of the metal plated. The second subprogram solves electroplating problems. The form of the Nernst equation used is E = E 0 - (RTlnQ)/(nF). The Nernst equation sub-program can solve the Nernst Equation for Standard Electrode Potential (E 0), actual potential (E), number of moles of electrons (n), reaction quotient (Q), and temperature in Kelvins. ElectrochemistryĮlectrochemistry designed to solve problems involving the Nernst equation as well as electolytic metal plating. Also, understand that the College Board is fully aware of the existence of programs such as these, which is one of the reasons why the AP tests are shifting from rote application of calculations to discussion and explanation of the theories at work.
However, as my father was fond of saying, "The tool is only as good as the person operating it." Use at your own risk. I am confident that the programs are sound. Please remember that no program is a substitute for comprehension of underlying theory.
You will need an unzipping program, and a TI link cable and the TI-Connect program for your computer.

All of the programs are are in zip archives, with a simple readme file.
Below I have linked to some useful programs, most of which I have written or modified. In addition, many calculations can be simplified (once the theory is mastered) by use of calculator programs. They are used in conjunction with the lab component, where we do many labs with the Vernier LabPro and Vernier probes. The TI-83plus/TI-84plus graphing calculators are used extensively in our AP Chemistry program. Programs for TI-83plus/TI-84plus Calculators
