what is displacement reaction? ?​

Answer 1

Answer:

It is the reaction in which a more reactive element displaces a less reactive element from its salt.

Ex: CuCl2 + Mg ----> MgCl2 + cu

Displacement Reaction

→ It is also known as single-displacement reaction. In this reaction, when two or more elements react, the most active element displaces the less active element from the other reactant and form the product(s)

${A \: + \: BC \: → AB \: + \: C}$

In the above example, A is more active than B. So, it displaces the less reactive B from BC, and form AB and C as products

• When an iron nail is added to the copper sulphate solution, iron being more reactive displaces copper from the copper sulphate solution. As a result, iron sulphate solution is formed as product. The copper then gets deposited on the nail.

CuSO$_{4}$ + Fe → FeSO$_{4}$ + Cu

• When copper reacts with silver nitrate, copper nitrate and silver are formed as products.

2AgNO$_{3}$ + Cu → Cu(NO$_{3}$)$_{2}$ + 2Ag
