Functionality: 8/10 Great, fast, works well
Controls: 9/10 Very user-friendly
Efficiency: 10/10 Instant answers
Overall: 9/10 Awesome chemistry program!
This program is great for chemistry classes. It can give you the pH and pOH of any weak acid or base solution. It's also great because you can enter the initial value of [H+], [OH-], and your conjugate acids/bases. It really helps, especially with buffered solutions. This program was tested by me with various problems, and I could find no error! This is a must download for all your chemistry needs. I personally use this to check my work, so I don't have to do it again.
The next step for this program would be for it to be able to solve for any unknown, like an unknown Ka or Kb value using some known variables. Overall, this program brings out the full potential of the TI-86 in the Chemistry classroom. Great job Daniel and Morgan!
