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.
WebMar 29, 2024 · Buffers work by neutralising any added acid (H+ ions) or base (OH- ions) to maintain the moderate pH, making them a weaker acid or base. Let’s take an example of … WebHow do buffers stabilize pH? Buffers are solutions that contain a weak acid and its a conjugate base; as such, they can absorb excess H + ions or OH ions, thereby maintaining an overall steady pH in the solution. pH is equal to the negative logarithm of the concentration of H + ions in solution: pH = log[H +].
WebA buffer can stabilize pH and acidity because it contains a reservoir of acid and a reservoir of base. The acid can react with added base. The anion of the weak acid "behaves" as a … WebThis results in an erratic reading that might never stabilize in a reasonable amount of time.
