Explanation / Answer

a) The pH change would not be significant because we are in the presence of a carbonate buffer system.

anyway the calculation could be: pH=pKa - log (a-/ha)

pH = 6.1 - Log (0.01/0.0001)

ph= 4.1

b) kidneys can vary the content of extracellular HCO3, forming new HCO3- increased when the concentration of acid or excrete HCO3- when the medium becomes basic.
