Calculate the minimum concentration of the acid-salt pair needed to buffer a solution at a pH of 4.10 when 50 mL of 0.1 M NaOH is added.

Question

Please help this is for a titration lab that is due tomorrow!!!!!!!!!!

Answer 1

You may have waited too long to post this question, since the assignment is due today. And, in fact, we cannot answer this without additional information such as the pKa of the acid used in the buffer. Then,

pH = pKa + log [salt]/[acid]

4.1 = pKa + log [salt]/acid]
