Question

A buffer solution was prepared by dissolving 3.71 g Na2CO3 and 3.78 g NaHCO3 in 0.2 L distilled water.
a) Explain why a mixture of Na2CO3 NaHCO3 in water has a buffering action.
b) Calculate the pH of the solution.
c) Assuming that there is no change in volume, predict the pH of the solution (decreases/
increases) when 0.020 mol of NaOH is added to the solution?
