You need to produce a carbonic (H,CO3)/bicarbonate buffer solution that has a pH of 4.50. You already have a 0.50L solution that contains 0.20 moles of carbonic acid. How many moles of sodium bicarbonate will you need to add to this solution? What will be the new pH if 0.040 moles of sodium hydroxide are added? Ka = 4.5 × 10-7
