When to use H-H equation

Postby Alexis Elliott 1J » Sat Dec 03, 2016 2:18 pm

How do we know when to use the Henderson-Hasselback Equation? Is it for any time when the concentration of the acid equals the concentration of its conjugate base?

Also, can we use this equation in titrations or only for buffers?

We mostly use the H-H equation regarding buffers. This is because this equation involves a weak acid/base and its conjugate through a salt with the same anion (or cation).
