1
Q
What is redox short for?
A
Reduction-oxidation
2
Q
What are examples of chemical reactions that involve redox reactions?
A
Electrolysis, combustion, displacement of metals and voltaic cells (e.g. batteries, solar cells and fuel cells)
3
Q
What is oxidation?
A
Oxidation is the gain of oxygen in a chemical reaction. It is also the loss of electrons. (OILRIG)
4
Q
What is reduction?
A
Reduction is the loss of oxygen in a chemical reaction. It is also the gain of electrons. (OILRIG)
5
Q
What does a redox reaction involve?
A
Simultaneous oxidation and reduction - both processes happen at the same time in the reaction.
