Methods of Extraction and Linked to the Order of Reactivity Flashcards
1
Q
Which metals can be extracted by a reduction reaction with carbon?
A
Only metals that are less reactive than carbon
2
Q
Why is this?
A
More reactive elements form compounds more readily

A
Iron oxide
Zinc oxide
Tin oxide
4
Q
Carbon can only take the oxygen away from metals which are…
A
Less reactive than carbon itself is
5
Q
What has to be done with metals that are more reactive than carbon?
A
They have to be extracted using electrolysis
6
Q
What does electrolysis use?
A
Electricity to separate the metal from the other elements in the compound
