INTRODUCTION : The idea of the experiment is to determine which equation is correct. There are 2 equations of CuCo3 and I have to find out which gases are given off when CuCo3 is given off. The two equations are 1.2CuCo3(s) Cu2O +2CO2 +0.5O2 2.CuCO(s) CuO +CO2(g) I am going to heat the CuCO3 check the colour when it is heated, measure the volume of the gas given off and test whether it is oxygen or carbon dioxide by introducing a glowing splint. Background theory: Copper (ii) trioxocarbonate (IV), CuCo3, only exists as basic salts and occurs naturally as malachite (CuCO3.Cu(OH)2) and azurite Cu(OH)2CuCO3. The basic trioxocarbonate (IV) of copper,CuCO3.Cu(OH)2 is precipitated when NaCO3 is added to any copper (II) salt solution. It is blue green, insoluble solid and decomposes into copper (II) and carbon (IV) oxide on heating. It is also attacked by dilute acids to produce carbon (IV) oxide. Copper is a transition element. Copper is...
