Extracting Metals Flashcards
1
Q
What can we use to extract metals with oxygen in them?
A
reduction (displacement)
2
Q
Heating a metal oxide with carbon is the process of extracting a metal known as what?
A
reduction (displacement)
3
Q
When can we not use reduction?
A
When carbon is less reactive than the metal in the oxide
4
Q
Metals that are more reactive than carbon are extracted using what?
A
Electrolysis
5
Q
How do we extract titanium?
A
using displacement with either sodium or magnesium (both of which need to be extracted through electrolysis)
6
Q
How do we extract aluminium?
A
electrolysis
