When two or more than two substance react to each other then more reactive element displace the less reactive element from their compound.

e.g. Zn+H2SO4 -------> ZnSO4+H2

QUESTION -

What is displacement reaction?

ANSWER -

Displacement reaction may be defined as reaction in which highly active species displace less active species from its compounds.

$It \: is \: of \: two \: types,$

Single displacement : This is when one element trades places with another element in a compound.

These reactions come in the general form of:

A + BC ---> AC + B

One example of a single displacement reaction is when magnesium replaces hydrogen in water to make magnesium hydroxide and hydrogen gas:

$Mg + 2 H2O ---> Mg(OH)2 + H2$

Double displacement : This is when the anions and cations of two different molecules switch places, forming two entirely different compounds.

These reactions are in the general form:

AB + CD ---> AD + CB

One example of a double displacement reaction is the reaction of lead (II) nitrate with potassium iodide to form lead (II) iodide and potassium nitrate:

$Pb(NO3)2 + 2 KI ---> PbI2 + 2 KNO3$
