FAQs on Reaction of Iron Nails with Copper Sulphate Solution in Water (Chemical Reactions) Video Lecture - Science Class 9

1. What happens when iron nails react with copper sulphate solution in water?
Ans. When iron nails react with copper sulphate solution in water, a chemical reaction takes place. The iron nails displace the copper from the copper sulphate solution, resulting in the formation of iron sulphate and solid copper. This reaction is also known as a displacement reaction.
2. What is the balanced chemical equation for the reaction between iron nails and copper sulphate solution?
Ans. The balanced chemical equation for the reaction between iron nails (Fe) and copper sulphate solution (CuSO4) is: Fe + CuSO4 → FeSO4 + Cu This equation shows that one iron atom reacts with one copper sulphate molecule to produce one iron sulphate molecule and one copper atom.
3. What is the purpose of conducting the reaction between iron nails and copper sulphate solution?
Ans. The purpose of conducting the reaction between iron nails and copper sulphate solution is to demonstrate a displacement reaction. This reaction helps to understand the reactivity series of metals. It also illustrates how a more reactive metal can displace a less reactive metal from its compound.
4. How can the results of the reaction between iron nails and copper sulphate solution be observed?
Ans. The results of the reaction between iron nails and copper sulphate solution can be observed visually. Initially, the blue color of the copper sulphate solution will fade as the copper ions are displaced by iron ions. A reddish-brown solid copper will start to form on the surface of the iron nails. This solid copper can be seen as a deposition on the nails.
5. What other metals can react with copper sulphate solution in a similar way?
Ans. Other metals that can react with copper sulphate solution in a similar way include zinc and aluminum. These metals are more reactive than copper and can displace copper from its compound. The reactions of zinc and aluminum with copper sulphate solution would result in the formation of zinc sulphate and aluminum sulphate, respectively, along with the deposition of solid copper.
