Question

Use the Henderson–Hasselbalch equation to calculate the pH of each solution:

Part B

a solution that contains 0.775% C5H5N by mass and 0.950% C5H5NHCl by mass. ( Express your answer using two decimal places.)

Part C

a solution that is 12.0 g of HF and 22.5 g of NaF in 125 mL of solution (Express your answer using two decimal places.)

- Calculate the pH of the solution that results from each of the following mixtures.

Part A4

150.0 mL of 0.27 M  HF with 225.0 mL of 0.32 M  NaF .(Express your answer using two decimal places).

Part B4

185.0 mL of 0.12 M C2H5NH2 with 275.0 mL of 0.22 M C2H5NH3Cl (Express your answer using two decimal places.)
