When hydrated copper hydroxycarbonate, CuCO3.Cu(OH)2.yH2O is heated, it decomposes as shown. CuCO3.Cu(OH)2.yH2O(s) → 2CuO(s) + CO2(g) + (1 + y)H2O(g) In this experiment, you will heat hydrated copper hydroxycarbonate to decompose it. You will use your results to investigate the value of y. FB 4 is hydrated copper hydroxycarbonate, CuCO3.Cu(OH)2.yH2O.
