Question

What is dissociation Reaction?

Answer 1

Hint: We know that the dissociation reaction is a reaction in which larger molecules break down into smaller ones with releases of energy. Most of the dissociation reaction involves addition of energy in the form of heat or electricity.

Complete answer:
Dissociation reaction can be defined as a chemical reaction in which a compound breaks apart into two or more compounds. This reaction takes place in a reversible way where the molecules differentiate or break into smaller particles such as atoms, ions or radicals. Dissociation reaction can be recognized when there is only one reactant and multiple products and reaction is given by: $AB\to A+B.$ When a dissociation reaction takes place in water, due to the polar nature of water, the ionic compounds dissolve in it. The positive ions of the compound get attracted to the negative pole of the water molecule, while the negative ions of the compound get attracted to the positive pole of the water molecule.
When water molecules dissociate, it breaks into ionic crystals. This happens due to the attraction between positive and negative ions in the crystals and polarity of water. Degree of dissociation is defined as the phenomenon in which free ions are produced which carries current. In this the complexes break into smaller particles such as atoms, ions and radicals. When dissociation reaction takes place, it leads to a decrease in energy. The proportion of dissociation we should know the strength of the given compounds. High strength means the large dissociation of the compound.

Note:
Remember that the strong acid, base and salt dissociate completely in water, so their proportion of dissociation is high. Water is a polar compound, so it remains ionized as proton and hydroxide ions.
