When added to water, some of the acid molecules may donate their protons to water, forming A minus and the hydronium ion H3O plus.

Since pKa is a concept that describes something to do with acids, I should start by reminding you what an acid is. In this video I’ll explain the concept of pKa, which I know feels a bit abstract but once you know what it means you’ll understand how acids, bases and salts behave in water! And talking of water, get yourself a drink and let’s make a start. Welcome to Pharma Drama, the channel where we look at the science of healthcare and healthcare products. Simon Gaisford explains the concept of pKA:
