Buffering Agent

A buffering agent is a weak acid or base used to maintain the acidity (pH) of a solution near a chosen value after the addition of another acid or base. That is, the function of a buffering agent is to prevent a rapid change in pH when acids or bases are added to the solution. Buffering agents have variable properties—some are more soluble than others; some are acidic while others are basic. As pH managers, they are important in many chemical applications, including agriculture, food processing, biochemistry, medicine and photography.

Famous quotes containing the word agent:

    ... in doing our psychology, we want to attribute mental states fully opaquely because it’s the fully opaque reading which tells us what the agent has in mind, and it’s what the agent has in mind that causes his behavior.
    Jerry Alan Fodor (b. 1935)
