Copper nitrate is bright blue crystalline solid containing 3molecules of water of crystallisation.
When this blue solid is heated in a test tube it loses 3 molecules of water and condenses on the cooler part of the test tube forming green colour solid.
Cu(NO3)2.3 H2O → Cu(NO3)2 + 3H2O.
But on further heating upto a high temperature, it is decomposed into NO2, CuO and O2 gas.
2Cu(NO3)2 → 4NO2 + 2CuO + O2
