1ère – Physical and Chemical Sciences – The Oxidation and reduction reactions.
(presented by Prof. Robert Burk – Carleton University - Ottawa)
Oxidation of Copper : http://www.youtube.com/watch?v=1oVJ5E8kdWs
Reduction of Copper ion : http://www.youtube.com/watch?v=MRw91oBy2xs
1)
What kind of videos are these?
1st video :
2)
What solution does Prof. Burk pour onto the penny ?
3)
What are the reactants ?
4)
In which state are the Copper and Nitrogen elements when the reaction starts?
5)
What can be observed during the reaction ?
6)
What are the products ?
7)
In which state are the Copper and Nitrogen elements when the reaction is finished?
8)
The Copper element is said to be oxidized from Copper metal Cu to Copper ion Cu+2. Define then
what an oxidation is.
9)
The Nitrate ion is reduced. Define then what a reduction is.
10)
Write down the redox reaction equation and the 2 so-called half-equations.
11)
What do the audience laugh at several times during the video?
2nd video :
12)
What material is the nail made of ?
13)
What is the blue solution ?
14)
What can be observed ?
15)
What are the reaction products?
16)
Is the Copper element oxidized or reduced through this reaction?
17)
Write down the 2 so-called half-equations and the redox reaction equation.
18)
Conclude these 2 experiments. What is a redox reaction ?
