Buffer capacity rises to a local maximum at pH = pK a. The height of this peak depends on the value of pK a. Buffer capacity is negligible when the concentration [HA] of buffering agent is very small and increases with increasing concentration of the buffering agent. [3] Some authors show only this region in graphs of buffer capacity. [2]

A circular buffer can be implemented using a pointer and three integers: [4] buffer start in memory; buffer capacity (length) write to buffer index (end) read from buffer index (start) This image shows a partially full buffer with Length = 7: This image shows a full buffer with four elements (numbers 1 through 4) having been overwritten:
A branch of physics that studies atoms as isolated systems of electrons and an atomic nucleus. Compare nuclear physics. atomic structure atomic weight (A) The sum total of protons (or electrons) and neutrons within an atom. audio frequency A periodic vibration whose frequency is in the band audible to the average human, the human hearing range.

Good sought to identify buffering compounds which met several criteria likely to be of value in biological research. p K a : Because most biological reactions take place near-neutral pH between 6 and 8, ideal buffers would have p K a values in this region to provide maximum buffering capacity there.
A buffer day works like this… Instead of limiting your vacation sights to the time you’re traveling and physically out of town, make a plan to always (alway Why the ‘Buffer Day’ Is the ...
The ocean contains a natural buffer system to maintain a pH between 8.1 and 8.3. [11] The oceans buffer system is known as the carbonate buffer system. [ 12 ] The carbonate buffer system is a series of reactions that uses carbonate as a buffer to convert C O 2 {\displaystyle \mathrm {CO_{2}} } into bicarbonate . [ 12 ]
