WebJul 5, 2024 · A pH buffer is a solution which resists pH change when acid or base are added to the solution. That doesn’t mean that the pH doesn’t change at all, but that the pH change is much smaller than a comparable solution without buffering function. An acidic buffer is a buffer that has an initial pH less than 7. WebA buffer solution is typically composed of a weak acid and its conjugate base. There are three major buffer systems that are responsible for regulating blood pH: the bicarbonate buffer system, the phosphate buffer system, and the plasma protein buffer system.
