WebHere the buffer also serves to neutralize the base. As the above example shows, a buffer works by replacing a strong acid or base with a weak one. The strong acid's proton is replaced by ammonium ion, a weak acid. The strong base OH-was replaced by the weak base ammonia. These replacements of strong acids and bases for weaker ones give … WebThe conjugate base of a strong acid would be an exceedingly weak base and so it would be severely limited in neutralizing additional acid. Essentially the addition of more acid would lower the pH even more so. The purpose of a buffer is to resist these drastic changes in pH so a strong acid buffer wouldn't really be achieving that. WebThe number of moles of the weak acid and its conjugate base must be significantly large compared to the number of moles of strong acid or base that may be added. The best buffering will occur when the ratio of [HA] to [A-^\text{-}-start superscript, start text, negative, end text, end superscript] is almost 1:1. code promo happy ears
