Question

You are provided with two containers made up of copper and aluminium you are provided with the solution of dilute hcl dilute hn o3 dilute zn cm and h2o in which of the above containers this solution can be kept

Answer 1

#Aluminium containers are safe as hno3 reacts with Al to form an oxidd layer which makes it passive for further attack and thus it can be easily transported in it as compared to cu...

hope it helps you out dude

Answer 2

Copper container:

1.HCl can be kept as no reaction takes place due to lower reactivity of copper.

2.HNO3 can be kept as no reaction takes place due to low reactivity of copper than hydrogen.

3. ZnCl2 can be kept as Zn is placed above copper in reactivity series of metal and hence no reaction occurs.

4. H2O can be kept due to the above reasons.

Aluminium container:

1. HCl cannot be kept as aluminium being more reactive than hydrogen displaces it from its solution and reaction occurs.

2. HNO3 cannot be kept as aluminium being more reactive than hydrogen displaces it from its solution and reaction occurs.

3. ZnCl2 cannot be kept as aluminium being more reactive than zinc displaces it from its solution and reaction occurs.

4. H2O:Aluminum does not react with cold or hot water and hence water can be kept in aluminium container.
