Does degree of dissociation depend on current?

Does degree of dissociation depend on current?

The Degree of dissociation does not depend on catalyst.

Does degree of dissociation depend on pressure?

The degree of dissociation of PCl5 decreases with increase in pressure.

What are the factors which govern the degree of dissociation of an electrolyte?

The extent to which an electrolyte dissociates into ions is known as degree of dissociation or ionization and depends upon the following factors: (1) Nature of the electrolyte, (2) Temperature, (3) Dilution, (4) nature of the solvent, and (e) presence of other ions.

Why does degree of dissociation of weak electrolyte increase?

When more amount of solvent such as water is added to the solution, it results in dissociating the molecules into ions of a weak electrolyte. Thus, the degree of dissociation of weak electrolyte increases upon dilution.

What are the degree of dissociation?

The degree of dissociation is the phenomenon of producing free ions carrying current, which at a given concentration is dissociated from the fraction of solute.

What is meant by degree of dissociation?

The degree of dissociation is the phenomenon of generating current carrying free ions, which are dissociated from the fraction of solute at a given concentration.

Why degree of dissociation is always less than 1?

There are two dissociations, governed by two different equations and two different equilibrium constants. The first dissociation has a degree of dissociation of 1 because sulfuric acid is a strong acid. The second dissociation has a degree much less than 1 because is a weak acid.

What are the factors that determine the degree of dissociation of a weak acid?

1 Answer

  • FACTORS AFFECTING THE VALUE OF DEGREE OF DISSOCIATION :
  • (1) Dilution → α ∝ √V so on dilution, α increases.
  • (2) Temperature → On increasing temperature ionization increases so, α increases.
  • (3) Nature of electrolyte.
  • (i) Strong electrolyte : α = 100\%
  • (ii) Weak electrolyte: α < 100 \%
  • (4) Nature of solvent.
