Demonstration

Aluminum and iron (III) oxide react to produce molten iron, aluminum oxide, and a tremendous amount of heat.

The non-reaction of potassium chloride with sucrose is contrasted with the reaction of potassium chlorate with sucrose to illustrate the importance the structure of anions and of nomenclature details.

An activity series of metals is induced from the redox reactions of various metals in ionic salt solutions.

Limiting Reactant: Reaction of Mg with HCl The amount of hydrogen gas produced by the reaction of three different quantities of Mg in the same numbere of moles of HCl is observed. Students are provided with the moles of magnesium and moles of hydrochloric acid and are asked to predict the relative amount of hydrogen gas produced in each reaction. Students determine the limiting reagent in each flask.

Two colorless solutions are mixed and after a brief induction period, the resultant colorless clear solution suddenly turns to a blue-black color. Changing the concentration of reactants in this clock reaction changes the induction period. This demonstration can be performed qualitatively or quantitatively.
