Question

R
2.) Aluminium is higher than iron in the reactivity series. To see if this was true, Ayesha took similar
sized pieces of aluminium and iron in test tubes. She added the same volume of dilute hydrochloric
acid to each. She noticed than
2. Initially there is more vigorous evolution of gas from the test tube having iron
After a couple of minutes, aluminium starts reacting much faster than iron and evolution of gas is
much more vigorous She was confused Can you explain to her why this happened?

b) Write two equations which you can raite on the basis of the above information​

Answer 1

Answer:

Because even though aluminum is more reactive than iron it does not corrode as much as iron. Aluminum reacts with oxygen in the air to form a layer of oxide which protects the aluminum from further oxidation. On the other hand the oxides of iron (Fe) tend to fall away, exposing the unreacted iron to further oxidation. This will cause it to corrode, otherwise known as rust.
