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 … Meer weergeven "Biological buffers".
