Question 1
1 / -0

Theory of ionization was given by

A
Rutherford

B
Graham

C
Faraday

D
Arrhenius

Solution

Arrhenius proposed the theory of ionisation.
Question 2
1 / -0

An ionizing solvent has

A
Low value of dielectric constant

B
High value of dielectric constant

C
A dielectric constant equal to 1

D
Has a high melting point

Solution

higher the dielectric constant of a solvent more of its ionising power.
Question 3
1 / -0

The extent of ionization increases

A
With the increase in concentration of solute

B
On addition of excess water to solution

C
On decreasing the temperature of solution

D
On stirring the solution vigorously

Solution

α ∞ dilution of solution.
Question 4
1 / -0

Which is generally true about ionic compounds

A
Have low boiling point

B
Have low melting point

C
Soluble in non polar solvents

D
Conduct electricity in the fused state

Solution

Generally ionic compound are conduct electricity in fused state.
Question 5
1 / -0

At infinite dilution, the percentage ionisation for both strong and weak electrolytes is

A
1%

B
20%

C
50%

D
100%

Solution

According to Ostwald’s dilution law because degree of ionization is directly proportional to the dilution.
Question 6
1 / -0

The degree of ionization of a compound depends on

A
Size of solute molecules

B
Nature of solute molecules

C
Nature of vessel used

D
Quantity of electricity passed

Solution

The degree of ionisation of a solute depends upon its nature, concentration, and temperature.
Question 7
1 / -0

Acetic acid is a weak electrolyte because

A
Its molecular weight is high

B
It is covalent compound

C
It does not dissociate much or its ionization is very less

D
It is highly unstable

Solution

It is a weak electrolyte because it’s ionization is very less.
Question 8
1 / -0

In which of the following dissociation of NH₄OH will be minimum

A
NaOH

B
H₂O

C
HN₄CL

D
NaCL

Solution

When we add NH₄OH in NH₄CL solution ionization of NH₄OH is decreased due to common ion effect.
