Um, so I got some science homework to find out what happens to metals when they react with carbonates?I've tried google, but I can't find anything lol so I thought i'd come ask the pit, seeing as none of my friends have had any luck with this homework either.

Thanks
Curses...i have nothing of interest to write in this here place.

ok here's a try,
FE + (CO3)2 = FE2CO3
i dont know, I forgot chemistry after i took Business Management..

Since carbonates in water are acidic, a redox reaction I'd guess? Don't know if that's the correct term in English though.

The only thing I know is that they dont react so good when they are in water

This would happen, if the carbonate was aqueous.


Carbonate is a cation with a -2 charge, so it would form an Ionic bond with a metal, the formula depending on the charge of the anion.

Carbonates are anions, metals are cations.

It depends what the 'carbonate' is bonded to; if it's a metal which is lower in the reactivity series, then it would be replaced by iron.

If it's some sort of carbonate dissolved in solution, hexane probably, because carbonates won't dissolve in water; then the free anions in solution might react with iron metal to form ferrus carbonate.

It all depends on the entropy of the reaction with which the carbonate is taking place. If the entropy of the universe increases with the overall reaction, then it will take place.
Entropy of the universe = entropy of the system + entropy of the surroundings.

Active metal + carbonate = some form of salt + water + Co2
