Question

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

Answer 1

Answer:

In a displacement reaction, a more reactive element replaces a less reactive element from a compound. ... In a displacement reaction, one displacement takes place. A + BX → AX + B. In a double displacement reaction, two displacements take place to complete the reaction.

Double displacement reactions generally take place in aqueous solutions in which the ions precipitate and there is an exchange of ions. For example, on mixing a solution of barium chloride with sodium sulphate, a white precipitate of barium sulphate is immediately formed. These reactions are ionic in nature.

Answer 2

Answer:

displacement reaction-The reaction in which a highly reactive else displaces a low reactive element from its compound, is called displacement reaction.

while.....

Double displacement reaction - The reaction in which exchange of ions and charges takes place in a reaction, is called double displacement reaction.
