Separating metals

Question 1

What is oxidation (metals)

Answer 1

Gaining oxygen

Question 2

What is reduction (metals)

Answer 2

Loss of oxygen

Question 3

How are metals separated using carbon

Answer 3

If the metal is less reactive than carbon, carbon will displace the metal from its compound

Question 4

What is the reactivity series

Answer 4

Group 1
Group 2
Group 3
Carbon
Transition metals
Copper
Backwards L

Question 5

What is oxygenation (electrons)

Answer 5

Losing electrons

Question 6

What is reduction (electrons)

Answer 6

Gaining electrons

Question 7

What is electrolysis

Answer 7

Separation of metals into the original atoms using electricity

Question 8

Why can solids not undergo electrolysis

Answer 8

In a solid the metal can not separate into its ions and then atoms
They are in fixed positions and cannot move

Question 9

Explain the steps of electrolysis

Answer 9

An electric current will pass through the electrolyte (molton or dissolved) and the ions will move to the corresponding electrode (cathode or anode)
The positive ions will move to the cathode and the negative ions will move to the anode

Question 10

Products at the anode (solution)

Answer 10

Halide ions
Or Oxygen

Question 11

Products at the cathode (solution)

Answer 11

Less reactive than hydrogen
Or hydrogen
