Buffer capacity falls to 33% of the maximum value at pH = pK a ± 1, to 10% at pH = pK a ± 1.5 and to 1% at pH = pK a ± 2. For this reason the most useful range is approximately p K a ± 1. When choosing a buffer for use at a specific pH, it should have a p K a value as close as possible to that pH.

Trello is a web-based, kanban-style, list-making application developed by Atlassian. Created in 2011 by Fog Creek Software , [ 5 ] it was spun out to form the basis of a separate company in New York City in 2014 [ 6 ] [ 7 ] [ 8 ] and sold to Atlassian in January 2017.
Tower defense is seen as a subgenre of real-time strategy video games, due to its real-time origins, [2] [3] even though many modern tower defense games include aspects of turn-based strategy. Strategic choice and positioning of defensive elements is an essential strategy of the genre.
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:
However, ammonium acetate is a dual component buffer system, which buffers around pH 4.75 ± 1 (acetate) and pH 9.25 ± 1 (ammonium), but it has no significant buffer capacity at pH 7, contrary to common misconception.
In computer science, a data buffer (or just buffer) is a region of memory used to store data temporarily while it is being moved from one place to another. Typically, the data is stored in a buffer as it is retrieved from an input device (such as a microphone) or just before it is sent to an output device (such as speakers); however, a buffer may be used when data is moved between processes ...
added a section on buffer capacity; added simple and universal buffer mixtures; added four significant references; The applications section does not, at present, do the topic justice, I don't have the time to do this. See acid dissociation constant for some other applications, with references. Petergans 18:47, 27 August 2008 (UTC)
