It should be noted that very small amounts of liquid were present on the watch glass. Afterwards, the same process was done for component Y with water instead of dichloromethane and decanted into a crucible and cover. It was apparent for both the removal of component X and component Y that the aqueous solution could not be removed from the test tube in entirety. After three washes, the crucible and cover was heated to evaporate the water. Similarly the crucible and cover were weighed and the difference between the clean crucible and the crucible with sample gave component Y’s mass, and from that the percent composition of the sample of Y. The remaining substance in the test tube was heated to evaporate any remaining solvents. The test tube and solid was measured. This solid ideally should be mainly component Z. However after the third wash with water for component Y, the remaining solid sample seemed to dissolve completely into the water. After heating and evaporation of the water, no solid was observed at the bottom of the test
