How do you find the pH of a buffer solution?

By measurement?


Of course, we can write the buffer equation:

#pH=pK_(a) + log_10{[[A^-]]/[[HA]]}#

And of course we can use this to model the solution behaviour in particular circumstances. However, all science relies on measurement. We must measure the #pH# if we wish to see if that equation holds true.
