By combining substances with pKa values differing by only two or less and changing the pH, a variety of buffers is usually received. Citric acid can be a valuable element of the buffer combination since it has three pKa values, divided by fewer than two.

This success from The reality that the 2nd and 3rd conditions turn out to be negligible at really very low pH. This time period is unbiased from the presence or absence of a buffering agent.
