4. (12 pts) A buffer is created by mixing 50.0 mL of 0.50 M C6H5N and 40.0 mL of 1.0M HC.HSNCI. What is the final pH of the solution if 20.0 mL of 0.50 M KOH is added to the buffer at 25 °C? K(C6H5N) - 1.4 x 10-9 To receive full credit, all work must be explicitly shown, including the relevant neutralization and hydrolysis chemical reactions that are occurring, and do not use the Henderson-Hasselbalch equation.

1)Which expression is the correct form of the Henderson-Hasselbalch equation? pH = pKa + log([base]/[acid]) pKa = pH + log([base]/[acid]) pH = pKa − log([base]/[acid]) pH = pKa + log([acid]/[base]) 2) Use the Henderson-Hasselbalch equation to calculate the pH of a buffer solution prepared by mixing equal volumes of 0.220 M NaHCO3 and 9.00×10−2 M Na2CO3. (Ka values are given in Appendix C.) Express your answer using three significant figures.

A 50 mL sample of 0.20 M propionic acid buffer (pKa 4.87 according to Google) has an initial pH of 4.77. After an unknown amount of 0.25 M HCl is added to the buffer, its pH has been lowered to 4.47. Using the Henderson-Hasselbalch equation, determine what volume of HCl was added to the buffer to cause the pH change, as well as the mass of Pr- necessary to return the buffer to its original pH.
