Emergeny, chemistry help
Hey guys im in gr 11 and i need help in chem
we did a lab and reacted Iron and Copper (ii) sulfate but nothing happened even though iron is higher on the activity series

kk thnx alot everyone
helped big time
[quote=spring02]When something is oxidized, it means it loses its electrons. generally, metals become oxidized in a reaction as they lose their electrons to the non metal part of the compound. Aznseal has a point where the iron loses its electrons to oxygen. This makes iron become oxidized, and therefore inhibiting its ability to react with other chemicals[/quote]
wooot ok thnx and thnx alot aznseal, but one more thing, the iron fillings looked normal, like they werent rusted
and the answer is the same thing for aluminun right ?
[quote=SinghNinja]meaning it wont react ?[/quote]
Yeah, because it'll already be "happy"
[quote=aznseal]If it's exposed to O2 for too long, it'll already have been oxidized.[/quote]
meaning it wont react ?
[quote=SinghNinja]nah the lab is right
teacher said it has something to do with iron being exposed to oxygen too long,
but i still dont know how that causes it not to react with copper (ii) sulfate[/quote]
If it's exposed to O2 for too long, it'll already have been oxidized.
[quote=Sadaxer]... I don't really know. Weird. Is that the point of the lab, or did you make a mistake?
If done correctly, it should...[/quote]

You did the lab wrong.
The reaction should have occurred, producing aqueous FeSO4 and solid Cu
