Question 2: What is the maximum amount of acid and base that can be added to a buffer made by the mixing of 0.71 moles of sodium hydrogen carbonate with 0.24 moles of sodium carbonate without there being a significant change in pH?
The maximum amount of base that can be added will be equal to the amount of HCO₃⁻ (sodium hydrogen carbonate) is 0.71 moles.
The maximum amount of acid that can be added will be equal to the amount of CO₃²⁻ (sodium carbonate) is 0.24 moles.
