WebDec 19, 2024 · In other words, a buffer solution (also known as a pH buffer or hydrogen ion buffer) is an aqueous solution composed of a weak acid and its conjugate base, or vice versa. Buffer solutions are used in a wide range of chemical applications to maintain a nearly constant pH. Many living systems in nature use buffering to regulate their pH.
WebOct 7, 2024 · What Is a Buffer? There are two key terms associated with buffers. A buffer is an aqueous solution that has a highly stable pH. A buffering agent is a weak acid or weak base that helps maintain the pH of an aqueous solution after adding another acid or base. If you add an acid or a base to a buffered solution, its pH will not change significantly. steve johnson buffalo billsWebProperties of Buffer Solution. Buffer solutions are certainly resistant to changes in pH. However, the pH of a buffer solution can change if there is an addition of sufficient strong acid or strong base.
