Demonstrations

Oxidation Numbers

Oxidation numbers are numbers assigned to elements in order to determine whether the elements have undergone oxidation or reduction during chemical reactions

 

            

            Hydrogen Gas from the Reaction of Magnesium Metal with Acid

 

Oxidation and Oxidizing Agents

Oxidation is by definition the loss of elections by an element; an oxidizing agent is a substance which causes the electrons of the element to be lost during a chemical reaction

            

            Chemiluminescence

            Formation of Hydrogen Gas from Acids

            Light Flashes from Oxidation

            Oxidation of Zinc

            Preparation of Chlorine Gas from Bleach

 

Oxidizing and Reducing Agents

An oxidizing agent causes another substance to be oxidized; an oxidizing agent is itself reduced; a reducing agent causes another substance to be reduced; a reducing agent is itself oxidized

 

            

            Light Flashes from Oxidation

            Oxidation of an Organic Compound
