MnO4 (aq) + H2O2 (aq) → Mn2+ (aq) + O2 (g) (a) Sketch a flask containing an analyte solution before any potassium permanganate KMnO4 is added, list out all species present. (b) Once a stoichiometric amount of permanganate ion is added to the analyte solution (the equivalence point of the titration!), sketch the beaker with all the species remaining after the reaction goes to completion. (c) Sketch the flask one more time, past the equivalence point. How do you know when you have passed the equivalence point?

Precipitation Titration

Precipitation analysis is used to analyze drugs, and to measure the salt content in food and beverages. It is an important concept from the examination point of view many practical questions are asked on the topic. This topic is significant in the professional exams for both undergraduate and graduate courses, especially for
