Question

Q3. What is displacement reaction? Explain with the help of an exampl.​

Answer 1

Answer:

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. Example : Reaction of iron nails with copper sulphate solution.

Answer 2

$\huge \star \huge answer \star$

• A displacement reaction is the one wherein the atom or a set of atoms is displaced by another atom in a molecule. For instance, when iron is added to a copper sulphate solution, it displaces the copper metal. The above equation exists when A is more reactive than B.

Some other examples of displacement reactions which can occur are:

• zinc displacing iron ions from iron(II) sulfate solution.
• nickel displacing copper from copper(II) nitrate solution.
• copper displacing silver from silver(I) nitrate solution.
