Calculate the pH of a buffer solution that contains 0.25 M benzoic acid (C6H5CO2H) and 0.15 M sodium benzoate (C6H5COONa). (Ka = 6.5 x 10-5 for benzoic acid)
A buffer solution contains 0.41 mol of benzoic acid (HC7H5O2) and 0.43 mol of sodium benzoate (NaC7H5O2) in 2.50 L. The Ka of benzoic acid (HC7H5O2) is Ka = 6.3e-05. (a) What is the pH of this buffer? pH = (b) What is the pH of the buffer after the addition of 0.16 mol of NaOH? (assume no volume change) pH = (c) What is the pH of the original buffer after the addition of 0.05 mol of HI? (assume...
A buffer with a pH of 3.95 contains 0.19 M of sodium benzoate and 0.34 M of benzoic acid. What is the concentration of [H,+] in the solution after the addition of 0.060 mol HCl to a final volume of 1.4 L? Assume that any contribution of HCl to the volume is negligible. [H,O+]=
A mixture contains 0.250 M benzoic acid, a monoprotic acid (Ka = 6.28 × 10‒5), and 0.400 M sodium benzoate. How many mL of a HCl solution whose pH is 0.523 should be added to 500 mL of this buffer to change its pH from what it is to pH = 4.20?
