1. Write out the chemical reaction that occurs in the blood
buffer, H2CO3/NaHCO3, when:
a. NaOH is added
b. HCl is added
2. Is the carbonic acid and bicarbonate solution a
better buffer when acid (HCl) is added or when base (NaOH) is
added? Why?
3. Did the water or the
H2CO3/NaHCO3 solution act as a buffer when acid was added
dropwise?
4. Compare the
number of drops of acid that was required to reach the buffer
capacity of the water and the buffer solution.
