Redox reactions- chemistry Flashcards
1
Q
What is the displacement reaction between chlorine displacing iodine from potassium iodide?
A
Cl2 (aq) + 2KI (aq) = I2 (aq) + 2KCL (aq)
When this reaction happens electrons are passed from the iodine to the chlorine
Cl2 (aq) + 2I (aq) = 2Cl (aq) + I2 (aq)
- Chlorine is reduced (so it is an oxidising agent)
- Iodine in oxidised (so it is a reducing agent)
2
Q
What is a loss of electrons called?
A
- Oxidation
3
Q
What is the gain of electrons called?
A
- Reduction
4
Q
What is an oxidising agent?
A
- accepts electrons and gets reduced
5
Q
What is a reducing agent?
A
- donates electrons and gets oxidised
