In computer terms, a device used to store data temporarily, normally to compensate for differences in speed between system components (for example, a high-speed data acquisition board and main memory).
1) A solution whose pH changes only slightly on the addition of acid or alkali. Paper saturated with solution and then dried will show the same pH as the buffer solution. 2) An alkaline reserve in paper, usually a calcium carbonate filler which maintains the pH in the neutral or alkaline range by reacting with acidic gases from the environment or from the deterioration of the paper itself.
Substance that resists change in acidity or alkalinity.

A substance added to the water to increase the alkalinity. Increasing the buffer will also increase the pH.
A substance or mixture of substances (such as bicarbonates and some proteins in biological fluids) that in solution tend to stabilize the hydrogen-ion concentration by neutralizing within limits both the acids and the bases, making the solution resistant to pH changes.
A substance added to the water to help maintain the pH value.
A chemical used to maintain a constant pH in a solution.
a solution that resists changes in pH when an acid or a base is added.
Substances which are capable of 'mopping up' excess acidity or alkalinity (excess hydrogen ions or hydroxyl ions) to maintain a constant pH.
A solution or liquid whose chemical makeup is such that it minimizes changes in pH when acids or bases are added to it.

a neutralizing solution; naturally occurring in the body, or used in pharmaceutics to protect medication from stomach acid degradation
The ability to resist changes in pH when an acid or base is added. For example, alkalinity buffers the stream against acid mine drainage. However, if the drainage uses up the alkalinity, the stream loses it's buffering capacity.
A solution of weak acids and their dissolved salts which is able to greatly minimize changes in the hydrogen ion concentration (acidity).

Alkaline substance (usually calcium carbonate) that is added to the paper to make it acid free. Close Window
a substance that, in solution, tends to prevent major shifts in pH by absorbing hydrogen ions when the solution becomes more acidic and by freeing hydrogen ions when the solution becomes more alkaline. Chemically a buffered solution usually contains a weak acid and the salt of that acid, or a weak base and the salt of that base. Biological buffered systems tend to be much more complex.
