Just cheching a chemical reaction
« on: February 18, 2010, 05:08:49 PM »
I have a chemical reaction project and I am going to do the following

CH3COOH + NaCO3 :rarrow: NaCH3COO,CO2, OH-

CuSO4 + NaHCO3  :rarrow: NaSO4, CO2, Cu(OH)2

CuSO4 + NaCO3  :rarrow:  NaSO4, CO2, CuO

I just wanted to verify with you guys at the forum if the products of the reactions are correct.

I think there are a couple of slight problems here.  For the first reaction, you can't go from having a neutral reactant side (net charge of zero), to a product with a net charge of -1.... so I think the product is sodium acetate (NaCH3COO), and HCO3 (carbonic acid).  I realize that carbonic acid can further break down into water and CO2, but the equation would have to be rebalanced in order to indicate that.

Foir the next two, the products should include Na2SO4, (NaSO4 is a charged species), so you will need to rebalance those equations as well.

So to summarize, you need to balance the equations so that the products that should form are possible.

Beware - HCO3 is not a correct formula of carbonic acid.

Reactions between copper ions and carbonates are rather complicated, with product being usually a mixture of carbonate and basic carbonates, with different amounts of hydration water.

In other words the CH3COOH with NaCO3 makes NaCH3COO and H2CO3 and the CO2 of the reaction is because H2CO3 dicomposes

Whoops... good catch on carbonic acid... my fault.
