By using the Henderson Hasselbalch equation,Calculate the Pka of lactic acid when the concentration of lactic acid is 0.01 molar. the PH is 4.80 and concentration of lactate is 0.87 molar
Answered by DrBob222
What's the problem? This is just a plug and chug problem
pH = pKa + log(base)/(acid)
pH = 4.80
pKa = ?
base = lactate = 0.87M
acid = lactic acid = 0.01M

4.8=x +log 0.87/0.01
4.8=x +log 87
4.8=x + 1.94
4.8-1.94=x
x=2.86
pKa= 2.86
