TL;DR

A single element replaces another in a compound, demonstrated with iron and copper sulfate.

Transcript

Single Displacement Reaction. A single displacement reaction is one in which a single element replaces another element which is in a compound. A plus BX gives B plus AX. Let us take an example to understand single displacement reaction. 2 iron nails. Copper sulfate solution. Put 2 iron nails in copper sulfate solution. After half an hour. After hal... Read More

Key Insights

Questions & Answers

Q: What is a single displacement reaction?

A single displacement reaction occurs when one element replaces another in a compound, showcasing reactivity differences.

Q: How is iron involved in the single displacement reaction with copper sulfate?

Iron displaces copper in copper sulfate, forming iron sulfate and depositing copper on the iron nails.

Q: What happens when iron nails are placed in copper sulfate solution?

After some time, a reddish-brown deposit of copper forms on the iron nails, while the copper sulfate solution turns greenish due to the displacement reaction.

Summary & Key Takeaways

• Single displacement reaction involves one element replacing another in a compound.

• Iron nails in copper sulfate solution result in copper deposition and color change.

• More reactive elements replace less reactive ones in single displacement reactions.
