Procedure:
1. Take six test tubes, write numbers on them.
2. Put Al in 1 and 4, Zn in 2 and 5, and Cu in 3 and 6.
3. Use the dropper drop some Hydrochloric acid in tube 1, 2 and 3.
4. Take another 3 test tubes above the tube number 1, 2 and 3 to collect the gas formed.
5. Repeat step 4 using Sulphuric acid instead of Hydrochloric acid, on test tubes 4,5 and 6 .
Concluison:
We have done this experiment and observed how the reaction between acids and metals is. Our experiments were successful. We couldn’t determine the hydrogen gas in Cu reaction with HCl and there was no reaction between them either. We couldn’t determine hydrogen gas in Al and Cu reaction with H2S04,but there was a reaction between Al and H2S04.
To make an experiments with acids are very dangerous, so that we wore safety glasses to protect our eyes from the acids.We turned the aspirator on to protect our lungs from
the poison gas, SO2
We determined the behaviour of Cu towards to acids and there was no reaction with neither HCl nor. But Zn gives reaction with acids.Those experiments explicitly show us that noble metals and semi noble metals, such as Al, Ag, Hg, Pt, Au,Cu do not give reaction with acids!
