Question

Ionisation depends upon what?
A. Volume
B. Pressure
C. Dilution
D. None

Answer 1

Hint:Ionization, also known as ionisation, is the process by which an atom or molecule gains or loses electrons to acquire a negative or positive charge, frequently in conjunction with other chemical changes. Ions are the name for the electrically charged atom or molecule. Ionization of weak electrolytes depends on the number of ions present per unit volume.

Complete step-by-step answer:In order to answer the provided question, we must identify the variables that affect how an electrolyte (an acid or a base) ionises.
There are various factors on which the ionisation of an electrolyte depends on. For example, temperature, dilution, presence of another solute etc.
Ionisation increases with increase in temperature. As the temperature rises, the molecules of the solute gain energy and become ionised. As a result, as temperature rises, so does ionisation.
The presence of same ion as the solute in a solution might alter how well another solute dissociates. The common ion effect is the reason for this.
As we keep on diluting a solution, its ionisation keeps on increasing. According to Le Chatelier's Principle, the equilibrium would move to the right if water were added. An increase in the percentage ionisation follows a shift to the right since it suggests that more electrolyte would be in the dissociated state. To explain this, consider that the concentration of ions in 1 L of solution is x mol/L. When we add 1 L of water in the solution, then the concentration of ion will reduce to 0.5x mol/L. Hence, the concentration of ions is reduced. Here according to Le Chatelier's Principle, equilibrium shift to the ions side to increase its concentration.
Volume and pressure do not affect ionisation. They have no relation with the ionisation process.

Option ‘C’ is correct

Note: Le Chatelier's principle, commonly known as Chatelier's principle, is a chemical principle that is used to foretell how a change in circumstances will affect chemical equilibria. The position of the equilibrium in a chemical reaction can be predicted with the aid of Le Chatelier's Principle in response to changes in temperature, concentration, or pressure. This is crucial, especially for industrial applications where it's crucial to predict and maximise yields.
