I have been doing this science prac at school and I have received some strange results. I measured the density of this metal, which leads me to believe it is Aluminium. Also, its silvery appearance supports this. When I have attempted to react it with Hydrochloric Acid, Sulfuric Acid and the nitrates/chlorides of a few metals, I have received some odd results.Despite having a high reactivity, the only substance it has reacted with so far out of all of the above is Tin Chloride. Am I doing something wrong? Is it possible that it isn't aluminium and rather a similar metal such as zinc? Thanks in advance :)
Aluminum is very reactive so what happens is that it has a coat aluminum oxide as soon as it comes in contact with oxygen the outer layer forms aluminum oxide Al2O3. That is why Aluminum does not rust. The Al203 coat protects it.
