Question

what is the double displacement explain with example

Answer 1

The reaction in which elements displace each another is known as Double displacement reaction.
EXAMPLE :- BaCl2 +Al2(SO4)3 BaSO4+ AlCl3

Answer 2

Double Displacement Reaction:-

=>The reaction in which exchange of ions between the reaction is called Double Displacement Reaction.

=> Reactant+Reactant=product +product

i.e AB+ CD ----->AC+ BD

=> In Double Displacement Reaction two chemical species are displaced or replaced.

For example:-

=>BaCl2 (aq) + Na2SO4 (aq)------>BaSO4 (s) + 2NaCL (aq)

=> Pb(NO3) (aq) +K.I (aq)----
>PbI2⬇+k(NO3)(aq)
