WebNov 7, 2024 · To make TBE buffer, you'll need just four substances. The remaining items on this list are equipment. The four substances required are EDTA disodium salt, Tris base, boric acid and deionized water. As for equipment, you'll need a pH meter and calibration standards, as appropriate. WebBuffer preparation is a common process in chemistry and biochemistry laboratories. A buffer solution is a mixture of a weak acid and its conjugate base or a weak base and its conjugate acid. Buffer solutions are used to help maintain a stable pH value of another solution that is mixed with the buffer.
WebThe function of a buffer is to keep the pH of a solution within a narrow range. As you can notice from the above equation, the ratio of [HA]/[A-^\text{-}-start superscript, start text, negative, end text, end superscript] directly influences the pH of a solution. In other words, the actual concentrations of A- and HA influence the effectiveness ...
