Question

Can we store copper sulphate in an iron container and why?
(A) No, because $Cu$ is more reactive than iron
(B) No, because iron is more reactive than copper, therefore reaction takes place
(C) Yes, because copper is less reactive than iron
(D) Yes, because copper is more reactive than copper

Answer 1

In a chemical reaction reactants reaction with each other at appropriate conditions to give products. The speed of some reactions is fast and the speed of some reaction is slow. And slow reactions can be made fast by using specific catalysts.

Complete step by step answer:
Copper is a metal denoted by the symbol $Cu$ and copper electropositive in nature it donates two electrons and oxygen is electronegative and takes two electrons from copper metal and ionic bonds formed between copper and oxygen. So to break this bond heat is supplied to it is an endothermic reaction. And the atomic mass of copper is $63.5u$.
Copper is a metal denoted by symbol $Cu$ and copper electropositive in nature it donates two electrons and sulphur is electronegative in nature takes two electrons from copper metal and an ionic bond is formed between copper and sulphur. So to break this bond heat is supplied.
In $CuS{O_4}$ copper metal is less reactive as compared to iron$\left( {Fe} \right)$ So when copper sulphate is placed in iron tank then displacement reaction take place and in copper sulphate copper metal is displaced by iron and the reaction is shown by-
$CuS{O_4} + Fe \to FeS{O_4} + Cu$
So copper sulphate is not placed in the iron tank.
Hence option B is the correct option.

Note:
Copper metal is soft in nature due to this it is ductile in nature and so it is very used in industry. And the electrical conductivity and thermal conductivity of copper metal is very high. So it is used in making wires copper is used.
Copper metal is solid in state at room temperature.
Copper sulphate is soluble in water because it forms hydrogen bonds with water molecules.
