Question

What is the colour of solution of copper sulphate when iron nails are dipped in it?​

Answer 1

Answer:

the colour of solution of copper sulphate when iron nails are dipped in it is greenish colour

Answer 2

A displacement reaction occurs when one of the atoms or a group of atoms in a molecule is displaced by another atom.

Explanation:

• When an iron nail is dipped in a copper sulphate solution, a brown copper coating forms on the iron nail's surface.
• The hue of the copper sulphate solution shifts from blue to light green.
• The fact that iron is more reactive than copper is demonstrated by this reaction.
• Copper is displaced from copper sulphate solution by iron, which flows into solution and forms ferrous sulphate solution.
• Some of the copper in the solution will interchange with the iron on the nail's surface. As a result, the copper will be applied to the iron nail.
• The blue copper sulphate solution will gradually transform into a green ferrous sulphate solution.
