How does a buffer solution maintains its ph

WebSep 14, 2024 · A buffer is a solution that can resist pH change upon the addition of an acidic or basic components. It is able to neutralize small amounts of added acid or base, thus maintaining the pH of the solution relatively stable. This is important for processes and/or reactions which require specific and stable pH ranges. WebSep 9, 2024 · The value 7 is neutral meaning the amount of H+ in a solution is equal to the amount of OH- in a solution. Pure water H 2 O, which can dissociate naturally into H + and OH - ions, would have a value of 7. Equation 1. H 2 O ↽ − − ⇀ H + + OH −. Table 1. The pH Scale. [H+] in mol/L. pH. [OH-] in mol/L.
