### pH of a buffer solution calculation

Do we have to use the Henderson-Hasselbach Equation when calculating the pH of a buffer solution? or we just use the ICE table ?

you can use an ICE table for a buffer solution; we had the example of HNO2+H2O = H3O+ + NO2- in lecture to find the pH of that particular buffer solution; we can probably easily use the Henderson-Hasselbach equation too (as long as you don't get the acid/base & it's conjugate flipped around!)

How do we calculate the pH of a buffer solution? Are there any good videos explaining this?

We only have to calculate the pH based on the ice table example used in the notes.

Exactly! But the Henderson-Hasselbach Equation is a shortcut that lets us skip the ICE table entirely! The equation can only be used for buffers though.

This is a vid I found helpful for the equation - and chem in general: https://www.youtube.com/watch?v=7Us44X98r-E
