Volumetric titrations are an accurate and precise analytical method, which explains their use in industrial and research settings and their inclusion in senior secondary chemistry curricula around the world. Students often have difficulty understanding the intricacies of titrations because they are novices being presented with a long list of detailed instructions, which hinders learning and leads to frustration. The main feature of this introductory volumetric titration activity is to sacrifice the usual precision and accuracy of the titration method by focussing on a relative comparison/ranking of two or more samples, without the determination of absolute concentrations. Students can thereby focus on mastering the fundamental technique, before worrying about the details.
