Answer 2

$\huge\underline\purple{Answer:}$

★The factors affecting on degree of Ionization:

• Nature of electrolytes
• Nature of solvent
• Dilution
• Temperature
• Common ion effect

•The explanations of the factors affecting the degree of ionization are explained below:-

$\red{★Nature.of.electrolytes-}$

Degree of ionization depends upon nature of electrolytes. Strong electrolytes have a high degree of ionization while weak electrolytes have a low degree of ionization

Nature of solvent- The ionizing power of the solvent depends upon its dielectric constant. Greater the value of dielectric constant greater will ionizing power of solvent and greater will be the degree of ionization.

$\red{★Dilution-}$

The degree of ionization increases with an increase in dilution. At infinite dilution, even the weak electrolytes are almost completely ionized.

$\red{★Temperature-}$

Degree of ionization increases with the increase in temperature.

$\red{★Common-ion-effect-}$

The suppression or degree of ionization of weak electrolyte by the addition of strong electrolyte having common ion is called common ion effect. Due to the common ion effect, the degree of ionization of weak electrolyte is decreased or suppressed.

★Therefore, the factors affecting the degree of ionization are explained above.
