By combining substances with pKa values differing by only two or much less and altering the pH, a wide array of buffers might be attained. Citric acid is often a helpful component of a buffer mixture mainly because it has a few pKa values, separated by a lot less than two.and only just a little is consumed in the neutralization reaction (which happ
