Question

Degree of ionization refers to the ratio of concentration of ionized compounds to neutral particles.
A. true
B. false

Answer 1

Hint: Ionization is the ability of a neutral compound or molecule to become an ion in solid, liquid and gas phase. As the ionization increases the number of ions increases.

Complete step by step answer:
The degree of ionization refers to the proportion of neutral particles with the charged particles which remain as ions in a gas or liquid phase. These ions are charged species containing certain positive or negative charges.
For acids and bases, the degree of ionization is the capacity of acid/base to ionize itself. If the value of degree of ionization is low means that the compound or molecule has low tendency or reluctance to get ionized. A high degree of ionization indicates that the compound is better ionized.
In ionization processes cases are possible by which an atom or molecule loses one or more electrons from its atomic orbital to attain a positive charge. Also it can gain electrons from less electronegative substituents to attain a negative charge.
Thus a molecule remains in the form of ions and not as a neutral molecule. The ions with positive charge obtained by losing electrons are called cation. The ions with negative charge which are obtained by gaining electrons are called anions.
For example the common salt i.e. sodium chloride is an ionic compound. In aqueous solution the sodium ion and chloride ion become free. Likewise the aqueous solution of sodium hydroxide contains free sodium ion and hydroxide ion.
The free ions are valuable for initiating a chemical reaction in organic synthesis. Hence the given statement is true i.e. degree of ionization refers to the ratio of concentration of ionized compounds to neutral particles.
So, the correct answer is “Option A”.

Note:
Complete ionization refers to complete separation of positive and negative ions of a molecule and the ions behave as individual particles after ionization. The percent dissociation of an acid/base varies with the concentration of the acid in solution. Normally with dilution the ionization increases.
