For the specific sample that you used, briefly explain why you think that the purity was not 100%.
The scraps of aluminium were not pure because of the oxidation of the surface of the container along with the coats of paint and plastic that covered the aluminum.
Name two other aluminum containing substances with which you are familiar that could be analyzed by the method used in this experiment.
Two other substance that contain aluminum that could be analyzed using this experiment are window frames and foils.
Why was it necessary in the procedure to equalize the level of liquid inside the buret and the liquid level outside the buret?
The total pressure will be read by using the barometer when both the water level in the barometer and outside
