If you need to prepare a buffer with a pH of 8.8, which one of the following acid/conjugate base pairs would you choose?
Consider a 250.0 mL solution of 0.20 M propanoic acid. Calculate the mass of sodium propanoate needed to produce a buffer with a pH of 5.11 assuming the volume does not change.
Calculate the pH of the solution that results from each mixture. a. 50.0 mL of 0.15 M HCHO2 with 75.0 mL of 0.13 M NaCHO2
Use the Henderson–Hasselbalch equation to calculate the pH of each solution.
c. a solution that contains 10.0 g of HC2H3O2 and 10.0 g of NaC2H3O2 in 150.0 mL of solution
Determine the pH of a 0.500 L solution of 0.15 M lactic acid-0.25 M sodium lactate buffer before and after 0.0050 mol NaOH is added. Assume the volume of X is negligible. The pKa of lactic acid is 3.86.
