WebA circular-buffer implementation may be optimized by mapping the underlying buffer to two contiguous regions of virtual memory. [disputed – discuss] (Naturally, the underlying buffer‘s length must then equal some … WebThe solution is a buffer because half of original acid has been converted to its conjugate base. Point A can be called a buffering region, specifically the first buffering region, as there will be a second. Point B. At point B, 1 mole of strong base has been added. Recall that the first proton is always more acidic than the second.
