Question

what is displacement reaction​

Answer 1

Explanation:

A single-displacement reaction, is a chemical reaction in which one element is replaced by another in a compound. It can be represented generically as:

Copper displaces dissolved silver from a solution. When a copper wire is dipped in a silver nitrate solution, solid silver precipitates out.

A + B-C → A-C + B

This will most often occur if A is more reactive than B, thus giving a more stable product. A and B must be either:

Different metals (hydrogen's behavior as a cation renders it as a metal here), in which case C represents an anion; or

Halogens, in which case C represents a cation.

In either case, when AC and BC are aqueous compounds (which is usually the case), C is a spectator ion.

Answer 2

Explanation:

Displacement reaction is a chemical reaction in which a more reactive element displaces a less reactive element from its compound. Both metals and non-metals take part in displacement reactions. Iron displacing copper in Copper Sulphate solution to form Iron Sulphate is one most common examples.
