Why blue colour of copper sulphate crystals disappears on heating ? |
| Answer» Blue colour of copper sulphate crystals disappears on heating because after heating it loses its water molecules and becomes anhydrous.the blue colour of copper sulphate was due to water molecules and now after losing water molecules it becomes white in colour ........... CuSO4.5H2O ------> CuSO4+5H2O.. CuSO4.5H2O was blue in colour and on heating it becomes CuSO4 that is white in colour . | |
