Limiting Reactant: Reaction of Mg with HCl

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.

Iodine Clock Reaction: Influence of Concentration on the Rate of Reaction

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.
