benzoic acid has PKa of 4.2 and MW 122g/mol. sodium benzoate has MW 144g/mol . a) mixing 50 grams of benzoic acid with 50 grams of sodium benzoate will lead to the same PH as mixing 200 grams of each. How do they differ in buffer capacity?B) could benzoic acid/ benzoate act as a buffer at PH 6.0? why or why not?C) what concentration of benzoic acid and sodium benzoate should be used to prepare a buffer that has a...
A chemist titrates 90.0mL of a 0.6722M benzoic acid HC6H5CO2 solution with 0.7570M NaOH solution at 25°C . Calculate the pH at equivalence. The pKa of benzoic acid is 4.20 . Round your answer to 2 decimal places. Note for advanced students: you may assume the total volume of the solution equals the initial volume plus the volume of NaOH solution added.
