Answer to Question #160000 in General Chemistry for James
Calculate the pH of a carbonate buffer system that contains 0.0065 M HCO3- and 0.0084 M CO32-. ( Ka of HCO3- is 4.7x0-11 )
3Calculate the pH of a carbonate buffer system that contains 0.0065 M HCO
PH = pKa - log(acid/salt)
= -log (4.7 × 10-11) - log (0.0065/0.0084)
= 10.33- (-0.11)
= 10.44
