Question about Texas Instruments TI-83 Plus Calculator
If you have the pH, and want to calculate the concentration that yields that value of the pH, you proceed as follows
c[H3O ] = 10^(-pH)
c[H3O ] : [2nd][LOG] [(-)] 8.23 [)] where [(-)] is the change sign key.
Here is a screen capture to show you how to calculate the pH (first example) and the concentration (2nd example)

That means that you know your calc crashed. This can be caused by taking out the batteries durring running time, happened just randomly. Well nothing to fear just press clear and it should go away but if it stays on that screen you have problems and is best to try some of these methods. Take out all the bateries and press and hold the on button for 30 seconds. Put the batteries back in and it should have reset. Warning you should archive everything incase this happens. To archive go to 2nd mem and hit enter to put a astrick next to the app (meaning archived)

I'm not specifically familiar with the TI83 or TI84 but I've used a lot of TI calculators in my time, so I'll give it a try. If your trying to find the antilog of a number in base 10 enter the number and hit the (10 to the X) button. If you're trying to find the antilog of a number in in base e (natural log), enter the number and hit the (e to the X) button.
