WebAnswer: Let's take an example of a buffer made up of the weak base ammonia, NH3 and its conjugate acid, NH4+. When HCl (strong acid) is added to this buffer system, the extra H+ ions added to the system are consumed by the NH3 to form NH4+. NH4+ is a weak acid therefore NH4+ = H+ (+) NH3. The equ... WebBuffers are chemicals that tend to resist changes in pH. Note that buffers do not prevent changes; they resist changes. Let’s see if we can figure out how this works. A typical buffer system is composed of a weak acid and the conjugate base of that acid. Remember, weak acids are those that do not dissociate completely but reach an equilibrium ...
