Question

Using equations showing the relationship between [acid], [conjugate base], and [buffer concentration], mathematically show the negligible change in pH when 2 microliters of 10M HCl is added to 100 mL of 50 mM phosphate buffer at pH 6.9. To address this problem, the following steps will be needed: (i) You will have to calculate the pH of the buffer after adding the 2 microliters of 10 M HCl (ii) To do this, calculate the new concentration of [acid] and [conjugate base] after the addition of 2 microliters of 10 M HCl, and (iii) To appreciate the effect of buffers, show the pH change in 100 mL of water after adding 2 microliters of 10 M HCl that does not contain the phosphate buffer ions. (show all calculation steps)
