Extracting Metals Flashcards
what is most nature metals like
impure metal compounds
metal ores
what does extracting metals involve
- breaking up the compound
- metal ions turning into metal atoms
more reactive metals are extracted using….
electricity
less reactive metals are extracted using what
heat
eg. silver, mercury, etc.
when extracting metals what is the name of the process
Reduction
-also, a reducing agent can be used to help with the process
what are the more reactive metals found later on the years
-Because electricity was needed to extract them but electricity was not invented by then………
…….so most of the high reactive metals are found on in the >1800
what are some reducing agents that can be used in the reaction
- Carbon (coke)……pure carbon
- Carbon Monoxide (CO).. needs to be done in a safe are eh. labs
- Hydrogen (H2).. needs to be done in a safe area.
describe how Iron can be extracted from Iron 3 oxide
Wet a match and cover it with iron 3 oxide and put it over the hottest part of the flame and let it burn and drop it on the mat and using a magnet the match covered in iron now should come up with the magnet.
