4.6 Introduction to Titration
In short
This topic introduces the fundamental principles of titrations as an analytical method to determine the amount of an analyte in solution. You must understand the roles of the titrant (known concentration) and the analyte.

What else do you need to know about Introduction to Titration?
The core conceptual depth lies in distinguishing between the equivalence point (the theoretical point where the analyte is totally consumed by the titrant) and the endpoint (the observable macroscopic event, such as a color change, that indicates the equivalence point has been reached). The scope is limited to identifying the equivalence point based on the amounts of titrant and analyte, assuming the reaction goes to completion.
How is Introduction to Titration tested on the exam?
You are assessed on your ability to represent chemical phenomena using appropriate graphing techniques, including correct scale and units (Science Practice 3.A). Exam questions may require you to connect particulate-level representations of a chemical system to different points on a titration curve (e.g., before titrant is added, at the half-equivalence point, at the equivalence point, and beyond the equivalence point). A common pitfall in related stoichiometric calculations is comparing mass to mass instead of mole to mole when determining limiting reactants or amounts consumed.
