Asked by Davis

Calculate the pH of a 75.0 ml solution containing 0.85 M lactic acid after the addition of 0.0225 moles NaL (assume a negligible volume change.)
Answered by DrBob222
Use the Henderson-Hasselbalch equation.
Lactic acid is the acid.
sodium lactate is the base.

DrBob--How do I determine the Pka value?
Answered by Davis
How do I figure out the Pka value?
Answered by DrBob222
Watch.
pH = -log(H^+)
pOH = -log(OH^-)
pKa = -log Ka
pKb = -log Kb
Do you get it? p means -log.
