Question

Q.. When is a chemical reaction considered a double displacement reaction ? Explain giving example.State a difference between displacement and double displacement reaction. ​

Answer 1

Answer:

1) When is a chemical reaction considered a double displacement reaction ?

A double displacement reaction occurs when there is an exchange of ions between the reactants (compounds ). According to reactivity series, the more reactive element DISPLACES the less reactive element in a compound.

2) State a difference between displacement and double displacement reactions ?

Displacement reaction is a chemical change, in which a more active element displaces a less reactivate element from its salt solution. Double displacement reaction is a chemical change in which two compounds exchange their radicals with each other to form new compounds. Example - Mg + H2So4 ---> MgSo4 + H2.

Answer 2

${\huge {\overbrace {\underbrace{\blue{ANSWER }}}}}$ 

⭕A double displacement reaction occurs when there is an exchange of ions between the reactants  (compounds ).⭕

➡️BaCl2 + H2SO4 ----> BaSO4 + 2HCl⬅️

⭕In displacement reaction

In displacement reactionAccording to reactivity series, the more reactive element DISPLACES the less reactive element in a compound.

➡️Fe + CuSO4 ---> FeSO4 + Cu⬅️

✴Whereas in double displacement reaction, there is an EXCHANGE OF IONS, it's like BOTH THE ELEMENTS displace each other. In simple terms, exchange of ions.✴
