Question

During an experiment Amit observed that blue colour of aqueous copper sulphate solution changed to
pale green by immersing a metallic rod for sometime.
a)Which metallic rod Amit might have immersed in the solution and what color would be observed on the
rod.
b) Mention the type of reaction in this case.

Answer 1

a) The type of rod is probably a zinc rod and the color of the rod will change to Orangish brown.
b)The reaction is a displacement reaction.

Answer 2

Answer:

• The experiment is being done with a rod in a solution (that has copper in it) and since there is reaction taking place.
• Hence the rod that would have been immersed would be a zinc rod there by displacement of copper from zinc would have taken place the colour of rod would have been orange or near to orange colour.
• The displacement of Copper and Zinc caused the solution of blue colour to turn green while the reaction is taking place.
• The kind of reaction needs to be discussed and in this case this reaction is a displacement reaction due to displacement of molecules from one solution to another .
