WebbA buffer is a mixture of a weak acid and its conjugate base or a weak base and its conjugate acid. The two forms of the buffer are called the buffer pair. In Brønsted-Lowry nomenclature, for a weak acid, the acid form is called HA and is defined as the H + donor. The base form is called A − and is defined as the H + acceptor. Webb6 juli 2024 · A buffer is a substance that prevents marked changes in the pH of a solution when an acid or base is added to it. Most of the body fluid buffer pairs consist of a weak acid and a salt of that acid for example 1. Bicarbonate pairs NaHCO3/H2CO3 and KHCO3/H2CO3 2.
