Question

What is the difference between electrolytic dissociation and ionization?

Answer 1

Hint: We know that the dissociation is breaking up of a compound into simple constituents. Ionisation of a compound is the breaking of the compound into its constituent ions. Covalent compounds get ionised while ionic compounds get dissociated.

Complete step by step answer:We know that in electrolytic dissociation, the separation of ions present in the solution of ionic compounds is done by passing an electric current. In electrolytic dissociation, the addition of an electrolyte causes the compound to break-up into ions.
Electrolytic dissociation produces charged particles or electrically neutral particles. Electrolytic dissociation is exhibited by ionic compounds. Electrolytic dissociation is a reversible process.
Electrolytic dissociation is possible when there are ionic bonds present in a compound.
Examples of covalent compounds are potassium chloride $\left( {{\text{KCl}}} \right)$, lead bromide $\left( {{\text{PbBr}}} \right)$, etc.
We know that in ionization, the positively or negatively charged ions are produced from the molecules which are not in the ionic state initially. During ionization, the atom or molecule gains a positive or negative charge by losing or gaining electrons. The charged atom or molecule is known as an ion.
Ionization is exhibited by covalent compounds. Ionization is an irreversible process.
Ionization is possible when there are covalent bonds present in a molecule.
Examples of ionic compounds are hydrochloric acid $\left( {{\text{HCl}}} \right)$, carbonic acid $\left( {{{\text{H}}_{\text{2}}}{\text{C}}{{\text{O}}_{\text{3}}}} \right)$, ammonium hydroxide $\left( {{\text{N}}{{\text{H}}_{\text{4}}}{\text{OH}}} \right)$, etc.

Note:The electrolytes used for electrolytic dissociation are of two types: strong electrolytes and weak electrolytes. The electrolytes which dissociate completely are known as strong electrolytes while the electrolytes which do not dissociate completely are known as weak electrolytes. Examples of strong electrolytes are hydrochloric acid, sodium chloride, potassium hydroxide, etc. examples of weak electrolytes are acetic acid, phosphoric acid, carbonic acid, etc.
