Consider the 25.0 mL portion of pH=4.45 buffer solution prepared as described in question 4. Calculate the buffering capacity of it for the hydrochloric acid of known concentration (M = 0.123 mol/L). Hint: you are calculating how much of the strong acid (HCl in this case) you can add to the buffer portion before you see a significant pH change, so start with deciding which component of the buffer will be the buffering species against the strong acid. Then calculate how much of that species is present in the 25.0 mL portion of this buffer. For the sake of these calculations, consider the buffering capacity to be the maximum volume of the strong acid that can be added to the portion of your buffer before the buffering species in it is completely used up, and the buffer is ‘overwhelmed’. Provide the answer in millilitres, mL. Don't include units.
