Question

Mathew prepared a yellowish green solution of Ferrous Sulphate

in beaker A and placed a copper wire in it. What change will

he observe in the beaker after an hour?​

Answer 1

Answer:

Yellowish green color iron sulphate solution is formed. Beaker B- Copper is less reactive than iron and cannot displace the iron from the ferrous sulphate solution. So, no change is observed.

Answer 2

He will observe no changes in the beaker after an hour.

• In a reactivity series, the metals that occupy the top position are more reactive than the ones which lie at the bottom.
• Hence, as per the reactivity series Iron lies at a higher position than copper. Therefore, no displacement or change in reaction will be observed as Iron is more reactive than Copper.
• The beaker will remain yellowish-green because of Ferrous sulphate as no reaction will take place.
