Title: Adding Mg to Cu unknown, gas evolved.
Post by: msandra on July 20, 2004, 10:40:00 PM

Today we had another experiment, adding mg to Cu unknown which either be Copper (II) acetate. H2O or Copper (II) sulfate . 5H2O.

There are also gas evolved .

Mg(s) + Cu(CH3COO)2 --> Mg(CH3COO)2 (aq) + Cu (s)
Mg(s) + CuSO4 --> MgSO4 (aq) + Cu (s)

Again, I can't figure out what the gas are . CO2? or SO2?

Sorry to ask so many questions but i really do not understand. Hope one of you can help me.

thanks

it could be H2O(g) if you heated it quite a bit before reacting

no we didn't heat anything.
