Oxidating flame

When oxidation occurs in copper, on the other hand, the result is a greenish coating called copper oxide.

The alcohol is heated under reflux with an excess of the oxidizing agent.

This could mean a wax or polyurethane coating on a car, a layer of paint on metal objects or a quick spray of an anti-oxidant, like lemon juice, on exposed fruit.

Destructive oxidation cannot occur if the oxygen cannot penetrate a surface to reach the free radicals it craves. The stainless steel has a thin coating of another metal which does not contain free radicals.

This page looks at the oxidation of alcohols using acidified sodium or potassium dichromate(VI) solution.

This reaction is used to make aldehydes, ketones and carboxylic acids, and as a way of distinguishing between primary, secondary and tertiary alcohols.

As the oxygen burns up the free radicals contained in the paint, the finish becomes duller and duller.



Light the burner and adjust the flame to light blue. The burning of magnesium in air produces intense heat which can cause burns and initiate combustion in.… continue reading »
