The blue colour of copper sulphate solution is discharged when a rod of zinc is deppid in it.Explain.

The colour of copper sulphate solution-

Blue colour of copper sulphate solution is discharged by dipping an iron rod in it.

Explain why-(a) A green layeris formed on the surface of copper which is left exposed in moist air for a long period. (b) blue colour of the copper sulphate solution is discharged slowly when an iron rod is dipped in it. (c) Galvanised irono is not used as a fondstuff container.

Assertion (A): The colour of copper sulphate solution changes when a piece of zinc is dropped in it Reason (R): Copper is more reactive than zinc.

Give reasons for the following: Blue colour of copper sulphate solution is destroyed when iron filings are added to it.

Copper sulphate solution is green in colour.

The blue colour of copper sulphate starts fading when a zinc rod is dipped in ti. State the reason and write the chemical equation for the reaction involved.
