Thermal Decomposition of Carbonates

  1. Mar 14, 2009 #1

    I have a practical assessment tomorrow which deals with the Thermal Decomposition of a metal Carbonate.

    Is it possible to write Ionic Equations for the reaction? Ionic solids and solutions are involved, but the reactions seem to be Double Decomposition, especially the test for CO2

    Also, how is it possible to predict the state(solid, liquid,gas) of a chemical?

    CuCO3 + CuO --> CuO + CO2

    CO2 + Ca(OH)2 --> CaCO3 +H2O

    CuO + H2SO4 --> CuSO4 + H2O

    Some of these reactions take place in solution, so some reagents will be in the form of ions.

    Your first reaction has an unnecessary CuO on the reactants side.
