Question

What is a double displacement reaction ? Explain with an example.
A small amount of quick lime is added to water in a beaker.
(i) Name and define the type of reaction that has taken place.
(ii) Write balanced chemical equation for the above reaction and
the chemical name of the product formed.
List two main observations of this reaction.
​

Answer 1

Explanation:

DOUBLE DISPLACEMENT REACTION:

THE REACTION IN WHICH THE IONS OF REACTANT ARE EXCHANGED AND FORM A PRECIPITATE; IT IS CALLED DOUBLE DISPLACEMENT REACTION

EX: Baso4 + k2cro4 -- Bacro4+k2so4

1.) it is decomposition reaction

2.)caco3 ---Cao +CO2

3.)the product form is lime water and CO2

and when CO2 pass through freshly prepared lime water it turns milky

Answer 2

Answer:

The reactions which occurs with the help of exchanging the ions between two or more reactants to form products . It is called double displacement reaction.

E.g- Na2SO4 + BaCl2 -BaSO4 + 2NaCl

Cao + H2O= Ca(OH)2

this is a combination reaction in which only one one product is formed from two or more reactants .

This is already balanced.

The chemical name of that product that is formed is Calcium Hydroxide.

Hope . It helps you .
