Question
Could I get assistance with the following
example?
The buffering capacity of lake is predominately due to the carbonate system. If the temperature is 25°C,
the pH is 7.4, and the total alkalinity is 200 mg/L as CaCOs, what decimal fraction of the total alkalinity is
due to HCO; present in the water.
Kaz and Kaz for carbonic acid are 4.45 x 10-7 and 4.69 x 10-11 respectively.
