... • Notice that when the concentrations of acid and conjugate base in a solution are the same, pH=pKa. When you choose an acid for a buffer solution, it is best to pick an acid with a pKa that is close to the desired pH. That way you can have almost equal amounts of acid and conjugate base in the sol ...
