Question

A student added few pieces of aluminium metal to two test tube A and B containing aqueous solution of iron sulphate and copper sulphate. In the second part of her experiment, she added iron metal to another test tube C and D containing an aqueous solution of aluminium sulphate and copper sulphate.
In which test tube or test tube will she observe a colour change, On the basis of this experiment, state which one is the most reactive metal and why.

Colour change will occur in test tubes A, B and D..
Aluminium is most reactive metal as it displaces iron and copper both from their compounds.

Answer 2

There will be a colour change in the test tubes A, B and D.

On the final note, aluminium is effectively a very reactive metal since it can displace relocates copper sulphate and iron sulphate from its outcome solution.

Due to the soft, lightweight, and ductile, the thermal and electrical conductivity it has highly reactive on equotient.

The metal is protected by a surface layer of inert transparent layer

hope it helps!!!!!!!
