` The buffer capacity of a buffered solution is defined in terms of theamount of protons or hydroxide ions it can absorb without asignificant change in pH.` A buffer with a large capacity contains large concentrations of thebuffering components.` The pH of a buffered solution is determined by the ratio [A-]/[HA].The capacity of a buffered solution is determined by the magnitudesof [HA] and [A-].
