Question

How do you find the pH of a buffer solution?

Answer 1

By measurement?

Explanation:

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.
