Question

(a) What is the difference between displacement and double displacement reactions? Write equations for these reactions.
(b) What do you mean by a precipitation reaction? Explain giving an example.

Answer 1

Answer:

1. In displacement reaction one element displaces another element from its compound and takes its place therein.Double displacement : The reaction in which the constituent atoms of the reaction interchange by the decomposition of the two reactants, to produce new compounds are called double displacement reactions.
2. A precipitation reaction is defined as a chemical reaction in which two aqueous solutions on chemically combining with each other results into the formation of a solid insoluble substance known as precipitate. For example, In this reaction, AgCl is the precipitate that is formed.
