Problem 2PE
Calculating the pH of a Buffer
What is the pH of a buffer that is 0.12 M in lactic acid [CH3CH(OH)COOH, or HC3H503] and 0.10 Min sodium lactate [CH3CH(OH)COONa or NaC3H503]? For lactic acid, Ka= 1.4 x 10-4.
Calculate the pH of a buffer composed of 0.12 M benzoic acid and 0.20 M sodium benzoate. (Refer to Appendix D.)
