The ability of buffers to resist a significant pH change is called the buffering capacity. The buffering capacity of a buffered solution represents the amount of protons or hydroxide ions the buffer can absorb without a significant pH change. It clearly depends on the concentration of the buffering species in the buffer, as well as the amount of buffer solution being used. 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 #x27;t include units. 1.093
