In this video, we’ll go over the basics of buffers, including what a buffer is and how it works to resist changes in pH. We’ll also look at the components of a buffer, including weak acids, conjugate bases, and pKa, and introduce the Henderson–Hasselbalch equation to understand how buffer pH is determined.

In this section, we’re going to learn how to calculate the pH of a buffer. We’ll go over the three main scenarios you might encounter: when a buffer is already given, when a buffer is formed through a reaction, and when a buffer has a strong acid or base added to it. The key idea throughout all of these is recognizing when to use the Henderson–Hasselbalch equation and when a reaction needs to be accounted for first.

Understanding the ability of a buffer to resist pH change, and it is greatest when the buffer components are concentrated and present in similar amounts.

Breaking down and explaining how to start titration problems and highlighting the differences between the strong vs weak acids/bases.

A step-by-step tutorial on how to approach titration problems and explanation on how the type of titration in the problem affects the process in which it needs to be solved.
