Chemistry Concepts - 16 How is this resolved? Buffers Group of materials (generally salts of weak acids and bases) that absorb or release H + depending on the condition so that proper pH is maintained. One of the most common buffers is the bicarbonate buffer. If a solution is too acidic, bicarbonate can combine with H + to form carbonic acid

Unformatted text preview: (HCO 3-+ H + ± H 2 CO 3 ) • If a solution is too basic, carbonic acid can combine with OH- to form bicarbonate + water (H 2 CO 3 + OH- ± HCO 3- + H 2 0) • Buffers are critical to the maintenance of life. Buffered systems mean that organisms can maintain a suitable pH environment in their cells and tissues....
