Routinely, buffers are cited by AP chemistry teachers as the topic that their students find the most challenging. Not necessarily equilibrium, but buffers. So, what about essentially largely avoiding the teaching of buffers completely, and approaching the problem from...

I quite often hear people say words to the effect of, “A buffer is a solution which does not change its pH when a strong acid or base is added to it.” Of course, this is not true, and instead I use the phrase, “A buffer is a solution that resists...

Following this post, I wanted to follow up with another quick note on the math of buffers as it relates to the new (when will I stop calling it that?), AP chemistry curriculum. If I am honest, this post repeats some of the stuff from the previous post on the subject,...

I think that there are (unfortunately) some useful, simple math things to know when it comes to buffers and H-H in the new AP chemistry curriculum. Obviously, it has always been crucial to know that when the ratio of weak acid to conjugate base (or weak base to...
