View source for Buffering agent

{{Stub}}
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.
