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:

Double displacement reaction is a type of chemical reaction where two compounds react ,and the position ions (cation) and the negative ions (anions) of two reactants switch places, forming new compounds or products.

Explanation:

Double displacement reaction is a type of chemical reaction in which a more reactive element displace a less reactive elements from its solution.

YOU CAN USE BOTH AS A DEFINE AS WELL AS DIFFERENCE. ..

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 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.✴
