Question

What is the difference between displacement and double displacement reactions? Write equations for these reactions.​

Answer 1

In displacement reaction, one element from its salt is displaced by a more reactive element e.g. in following example, Cu is displaced by Zn from CuSO4 because Zn is more reactive.

CuSO4 + Zn —> ZnSO4 + Cu

In double displacement reaction, exchange of ions takes place between two reactants to form new products.

Na2SO4 + BaCl2 —> BaSO4 + 2NaCl

☺ Hello mate__ ❤

◾◾here is your answer...

✒DEFINITION OF DISPLACEMENT REACTION::--

In a displacement reaction, a more reactive element replaces a less reactive element from a compound.

i.e. A + BX. -----> AX + B

where A is more reactive than B

Example :-

CuSO4 + Zn --> ZnSO4 + Cu

✒DEFINITION OF DISPLACEMENT REACTION::--

In a double displacement reaction, two atoms or a group of atoms change places to form new compounds.

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

Example:--

Na2SO4 + BaCl ---> NaSO4 + 2NaCl
