  2. Buffer solution - Wikipedia

    en.wikipedia.org/wiki/Buffer_solution

    A buffer solution is a solution where the pH does not change significantly on dilution or if an acid or base is added at constant temperature. [1] Its pH changes very little when a small amount of strong acid or base is added to it. Buffer solutions are used as a means of keeping pH at a nearly constant value in a wide variety of chemical ...

  4. Good's buffers - Wikipedia

    en.wikipedia.org/wiki/Good's_buffers

    Good sought to identify buffering compounds which met several criteria likely to be of value in biological research. pK a: Because most biological reactions take place near-neutral pH between 6 and 8, ideal buffers would have pK a values in this region to provide maximum buffering capacity there.

  5. Conjugate (acid-base theory) - Wikipedia

    en.wikipedia.org/wiki/Conjugate_(acid-base_theory)

    One use of conjugate acids and bases lies in buffering systems, which include a buffer solution. In a buffer, a weak acid and its conjugate base (in the form of a salt), or a weak base and its conjugate acid, are used in order to limit the pH change during a titration process. Buffers have both organic and non-organic chemical applications. For ...

  6. Tris-buffered saline - Wikipedia

    en.wikipedia.org/wiki/Tris-Buffered_Saline

    Tris-buffered saline (TBS) is a buffer used in some biochemical techniques to maintain the pH within a relatively narrow range. Tris (with HCl) has a slightly alkaline buffering capacity in the 7–9.2 range. The conjugate acid of Tris has a pK a of 8.07 at 25 °C. The pK a declines approximately 0.03 units per degree Celsius rise in ...

  7. MOPS - Wikipedia

    en.wikipedia.org/wiki/MOPS

    MOPS (3-(N-morpholino)propanesulfonic acid) is a buffer introduced in the 1960s, one of the twenty Good's buffers.It is a structural analog to MES, [1] and like MES, its structure contains a morpholine ring.
