Ionic buffer
A buffer solution (more precisely, pH buffer or hydrogen ion buffer) is an acid or a base aqueous solution consisting of a mixture of a weak acid and its conjugate base, or vice versa. 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 … Meer weergeven Buffer solutions resist pH change because of a chemical equilibrium between the weak acid HA and its conjugate base A : When some strong acid is added to an equilibrium mixture of the weak acid and its conjugate … Meer weergeven Monoprotic acids First write down the equilibrium expression This shows that when the acid dissociates, equal amounts of hydrogen ion and anion are produced.

Web4 mei 2024 · A buffer is an aqueous solution used to keep the pH of a solution nearly constant. A buffer consists of a weak acid and its conjugate base or a weak base and its conjugate acid. Buffer capacity is the amount of acid or base that can be added before the pH of a buffer changes. WebThe main consideration when choosing a lysis buffer is whether the chosen antibody will recognize denatured samples. When this is not the case, it will be noted on the antibody datasheet, and buffers without detergent or with relatively mild non-ionic detergents (NP-40, Triton X-100) should be used.
