WebThe different pHs under investigation will be produced using buffer solutions. Buffer solutions produce a particular pH, and will maintain it if other substances are added. WebA buffer solution resists large changes in pH upon the addition of small amounts of strong acid or strong base. A buffer has two components: one that will react with added H+ and one that will react with added OH–. Usually these two parts are a weak acid and its conjugate base (or vice versa). spigot clear lag
