Carbonate Buffer System:

One crucial buffer in the Niagara River is the carbonate buffer system. This system involves the presence of carbon dioxide (CO2), carbonic acid (H2CO3), bicarbonate ions (HCO3-), and carbonate ions (CO32-). When acids enter the river, they react with carbonate ions to form more bicarbonate ions, which have a higher pH. Conversely, when bases enter the river, they react with bicarbonate ions to form more carbonate ions, which have a lower pH. This equilibrium helps maintain a relatively stable pH.

Other Buffers:

Other natural buffers in the Niagara River include phosphate buffer system and organic matter. Phosphate buffer system involves the presence of phosphate ions (PO43-) and dihydrogen phosphate ions (H2PO4-). Organic matter, such as humic acids, can also act as buffers by binding to acids or bases.
