Before we start with specific types of titrations, it would be a good idea to make sure we're on the same page. Titration is the slow addition of a substance to a solution through a buret. Titration is most commonly used to add acids to bases or bases to acids. There are three types of titrations that are covered in the Death Test unit: strong/strong, weak/strong, and polyprotic titrations. During a titration, a pH meter or an indicator is used to determine the pH at specific points in the titration. That said, let's move on to the simplest of titrations: Strong/Strong Titrations.
