What is buffering?
buffering definition: 1. present participle of buffer 2. to provide protection against harm 3. When a computer buffers. Learn more. Oct 08, · Buffering involves pre-loading data into a certain area of memory known as a “buffer,” so the data can be accessed more quickly when one of the computer’s processing units — such as a GPU for video games or other forms of graphics, or a CPU for general computer processing — needs the data. verb. buffered; buffering \ ?b?- f (?-)ri?. How to pronounce buffer (audio) \. Definition of buffer (Entry 3 of 4) transitive verb. 1: to lessen the shock of: cushion. 2: to treat (something, such as an acid solution) .
A buffer is a solution containing either a weak acid and its salt or a weak base and its salt , which is resistant to changes in pH. In other words, a buffer is an aqueous solution of either a weak acid and its conjugate base or a weak base and its conjugate acid.
A buffer may also be called a pH buffer, hydrogen ion buffer, or buffer solution. Buffers are used to maintain a stable pH in a solution, as they can neutralize small quantities of additional acid of base. For a given buffer solution, there is a working pH range and a set amount of acid or base that can be neutralized before the pH will change.
The amount of acid or base that can be added to a buffer before changing its pH is called its buffer capacity. The Henderson-Hasselbalch equation may be used to gauge the approximate pH of a buffer. In order to use the equation, the initial concentration or stoichiometric concentration is entered instead of the equilibrium concentration.
The general form of a buffer chemical reaction is:. As stated, buffers are useful over specific pH ranges. For example, here is the pH range of common buffering agents:. When a buffer solution is prepared, the pH of the solution is adjusted to get it within the correct effective range. Typically a strong acid, such as hydrochloric acid HCl is added to lower the pH of acidic buffers.
A strong base, such as sodium hydroxide solution NaOH , is added to raise the pH of alkaline buffers. In order to understand how a buffer works, consider the example of a buffer solution made by dissolving sodium acetate into acetic acid.
The equation for the reaction is:. If a strong acid is added to this solution, the acetate ion neutralizes it:. This shifts the equilibrium of the initial buffer reaction, keeping the pH stable. A strong base, on the other hand, would react with the acetic acid. Most buffers work over a relative narrow pH range. An exception is citric acid because it has three pKa values. When a compound has multiple pKa values, a larger pH range becomes available for a buffer. It's also possible to combine buffers, providing their pKa values are close differing by 2 or less , and adjusting the pH with strong base or acid to reach the required range.
Depending on the ratio between the compounds, the buffer may be effective from pH 3. A mixture of citric acid, boric acid, monopotassium phosphate, and diethyl barbituic acid can cover the pH range from 2. Share Flipboard Email. Anne Marie Helmenstine, Ph. Chemistry Expert.
