Unraveling Oxidation and Reduction: Exploring Chemical Reactions
Slide 1 - Diapositive
Learning Objective
At the end of the lesson, you will be able to understand oxidation, reduction, and displacement reactions and identify examples of these reactions.
Slide 2 - Diapositive
What do you already know about oxidation and reduction?
Slide 3 - Carte mentale
Slide 4 - Diapositive
Oxidation and Reduction
Oxidation is the gain of oxygen, while reduction is the loss of oxygen. These processes play a crucial role in chemical reactions.
Slide 5 - Diapositive
Reactions of Metals with Oxygen
Many metals react with oxygen to form metal oxides. For instance, magnesium burns in air to produce magnesium oxide.
Slide 6 - Diapositive
Example: Magnesium Oxide
The reaction of magnesium with oxygen can be represented as 2Mg(s) + O2(g) → 2MgO(s). This is an oxidation reaction as the metal gains oxygen.
Slide 7 - Diapositive
Displacement Reactions
Oxygen can be removed from metal oxides in chemical reactions. For example, in the reaction of copper oxide with carbon, oxygen is removed from the copper oxide and carbon is oxidized.
Slide 8 - Diapositive
Example: Copper Oxide Displacement
The reaction between copper oxide and carbon can be represented as 2CuO(s) + C(s) → 2Cu(l) + CO2(g). Here, carbon is oxidized and copper oxide is reduced.
Slide 9 - Diapositive
Interactive Activity: Identifying Oxidation and Reduction
Present students with chemical reactions and ask them to identify which components undergo oxidation and reduction.
