Hint:The degree of ionisation for a weak acid or base is determined by the \[pKa\] value and is specified by Henderson-Hasselbalch equations. The total number of dissolved, dissociated, and total moles affects the degree of ionisation.
Complete step-by-step answer:In order to know that the electrolyte's dissociation constant and degree of ionisation describe the substance's strength and other characteristics.
An electrolyte's degree of ionisation can be expressed as a percentage of the total number of molecules that dissociated into ions. It is determined by the quantity of molecules that are ionised and the quantity of molecules that are dissolved in water. Ionization levels can be expressed as decimal numbers and percentages.
Degree of dissociation of an acid for a very dilute solution is given by
$\alpha = \sqrt {\dfrac{{{K_a}}}{C}} $
The value of acid dissociation constant(Ka) is specific for each electrolyte. It also depends on temperature.
Consequently, the nature of solute molecules determines the degree of ionisation of a chemical.
Option ‘B’ is correct
Note: It should be noted that the strong electrolytes have a degree of ionisation value that is approximately one at normal dilution, whereas weak electrolytes have a value that is very close to zero. With an increase in temperature, an electrolyte in solution becomes more ionised and the degree of ionisation of an electrolyte falls uniformly in the presence of a strong electrolyte with a common ion.
