When to use the Henderson-Hasselbalch Equation

Can I use the Henderson-Hasselbalch equation when I have a weak acid that is being titrated by a strong base, but not all the way to the stoichiometric point? I guess my real question would be, is the HH equation valid when the volume (and thus molarity) of a system is changing (if I were to calculate the molarities of the weak acid and its conjugate base after the addition of the titrant), or does it only apply to systems with unchanging volume where the added strong base is a salt dissolved in the solution?

Yes, you can use it in this situation. Be careful when determining your concentrations of the conjugate acid/base pair.

So we will have the option of using the Henderson-Hasselbalch equation or the ice box on the final?

This equation is used for estimating the pH of a buffer solution.

Will we have to know this equation for the final? We haven't learned about it in lecture yet, right?
