Full explainer at https://www.chemistry-dictionary.com/titration/ - Most students think a titration is about the colour change. It is not; the colour change is just a timer going off. A titration is a counting exercise: you react a solution of unknown concentration against one you know exactly, and let the balanced equation do the arithmetic. This two-page visual guide covers the analyte and pipette, filling the burette with the standard solution, the indicator, the first reading, swirling in the titrant, catching the endpoint, calculating the titre, and converting it into a concentration with n = c x V. It also covers the two things that catch people out: treating the endpoint as the answer instead of the measurement, and forgetting the mole ratio in a 2:1 reaction. For high school and early college chemistry students.
