For each of the weak acids listed below, consider how you would make a buffer solution where the weak acid has a concentration of 0.5 M at equilibrium. Determine what molarity for each potassium conjugate base salt would need to be added to make 500 mL of an effective buffer with a pH of 5.32. Which acid would make the best buffer at this pH? Which conjugate base salt would be the most economical (cheapest) out of the three choices? ...
