Question

4. Why do the color & solution of copper sulahute change when we take a solution of
copper
sulphate in a beaker and put an iron nail in it?
anybody will give me right answer I will make that answer brainlist answer. ​

Answer 1

Answer:

Chemical reaction of iron nail withcopper sulphate solution in water. Irondisplaces copper ions from an aqueous solution of copper sulphate. ... Thus iron is more reactive thancopper. In this reaction, metallic iron isconverted into ferrous ion (Fe2+) and cupric ion (Cu2 +) is converted into metallic copper.

Answer 2

• When an iron nail immersed in the solution of copper sulphate than iron displaces copper from the solution of copper sulphate because iron is more reactive than copper. Therefore copper sulphate solution colour changes from blue to pale green.
