pH of a mixture

Calculate the pH of a mixture, for the solutions given below. Enter the initial concentration and volume for each solution and/or ...

... add acids/bases, not appearing in the table. Enter concentration, volume and pK, for each of the added solutions.

If the entered concentrations correspond to those in the final mixture, leave all volumes at zero.
NEW: pH of ampholytes can be calculated.
