When Iron nails are added to an aquous solution of copper sulphate, a ...
Explanation:
Introduction:
When iron nails are added to an aqueous solution of copper sulfate, a chemical reaction occurs known as a displacement reaction. In this reaction, iron displaces copper from the copper sulfate solution, resulting in the formation of iron sulfate and copper metal.
Explanation of options:
a) Blue color of the solution fades:
This statement is true. Copper sulfate solution is blue in color. When iron nails are added, the iron displaces copper from the solution, causing the blue color to fade.
b) Iron nails become brownish in color:
This statement is true. As iron displaces copper from the solution, copper metal is deposited on the surface of the iron nails. The brownish color observed is due to the formation of a thin layer of copper on the iron nails.
c) It is a displacement reaction:
This statement is true. A displacement reaction occurs when a more reactive element displaces a less reactive element from its compound. In this case, iron is more reactive than copper, so it displaces copper from copper sulfate, resulting in the formation of iron sulfate and copper metal.
d) Iron nails dissolve completely:
This statement is not true. Iron nails do not dissolve completely in the copper sulfate solution. Instead, they undergo a chemical reaction with copper sulfate to form iron sulfate and copper metal. The iron nails remain intact, although they may become thinner due to the loss of iron atoms during the reaction.
Conclusion:
Out of the given options, option 'D' is not true. Iron nails do not dissolve completely in the aqueous solution of copper sulfate. Instead, a displacement reaction occurs, resulting in the formation of iron sulfate and copper metal.
