pH Bаlаnce – Functiоn оf Buffers Study Guide Buffers аre a cоmbination of two molecules: a weak acid and its corresponding base. Buffers are therefore capable of stabilizing pH at any value depending on their buffering capacity. If the solution has a sudden increase of H+, the pH value would naturally lower. However, if a buffer is present, the base partner of the buffer would absorb the excess H+ in solution and bring the pH back to the stable pH value it sustains. Likewise, if the H+ in solution started to lower, the pH value will start to increase. However, when the buffer is present, the acid partner of the buffer will release more H+ to bring the pH back to the stable pH it sustains. Buffers are present in all biological organisms and thus play important roles in maintaining a stable pH.
