This is a program for finding pH, pOH, [H+] (Concentration of H+ ions)/ [OH-] (concentration of hydroxide ions). This WILL work on all of the TI-84 series of calculators, untested on the TI-83. All you need to do is input one of the values mentioned above, and the program will calculate the rest of the values. They are rounded to 3 decimal places, for ease of displaying on the TI-84+ screen. If the values go off-screen, or look messed up, please report this by reviewing the file. I will get it fixed and re-uploaded ASAP.

If you have any questions, comments or suggestions, PM me at or post a review on

Great! It doesn't require any extra setup and is easy to navigate. The menus are very clear and it runs quickly. I've double-checked the calculations it makes and as far as I can tell it all comes up correct. I use a TI-84+ SE and this program has been very useful!

Visuals (2/2): Gives good info page when first starting the program. I like formatting of the output information.
Speed (2/2): Pretty much instant. Can't say much more to change.
Ease of Use (2/2): Just enter what you know and it does all the rest.
Practicality (2/2): Depending on what you're needing to do, it cuts your calculations down from 3 to 1. Very helpful.
Other (2/2): Nothing to complain about here.

Overall: (10/10)
