PH calculates the pH of a water solution from the concentration and equi-
librium constant of the solute--if you're in general chem., 'gotta have it.




I originally wrote this program for the TI-81 when I was taking general
chemistry, but recently upgraded it for the TI-85.

PH is a simple program which calculates the pH, pOH, [H+], and [OH-] of a
water solution given the concentration and equilibrium constant of the 
solute.  The solute may be either an acid or a base.  In either case, the
equilibrium constant should be Ka (ie., if your dealing with a base, the
Ka of its conjugate acid).  

For this program, the equilibrium constant of H2O is taken to be 1.0*10^-14.
This program will calculate exact values for pH, etc., only for monoprotic
acids and bases assuming that K(H20) is 1.0*10^-14 (which, if I'm not
mistaken, occurs at 25 degrees celsius and 1 atm pressure).  Though not
exact for polyprotic acids and bases, PH produces values which are still
very close approximations (probably good to 3 or 4 significant figures).

If you have any questions or comments, please feel free to contact me.
