Question

Which will not affect the degree of ionization
A. Temperature
B. Concentration
C. Type of solvent
D. Current

Answer 1

Hint: The percentage of neutral particles that are ionised, such as those in a gas or aqueous solution, is known as the degree of ionisation. It can be interpreted as an acid or base's ability to ionise itself in the context of electrolytes. A weak electrolyte's degree of ionisation may be affected by a variety of conditions and additional substances.

Complete step-by-step answer:A weak electrolyte's degree of ionisation may be influenced by a variety of variables. Ionization, which is sometimes combined with other chemical changes, is the process by which an atom or molecule obtains a negative or positive charge by gaining or losing electrons. The degree of ionisation depends on how far along this process is.
The type of the solute, nature of the solvent, and temperature all affect how much ionisation occurs. A solute's type, concentration, and temperature all influence how ionised it is. Only a small portion of the weak electrolytes are soluble in solution. As a result, they do not fully ionise in solution. However, even weak acids begin to ionise at high dilutions. As a result, dilution increases along with the degree of ionisation.
Additionally, as the temperature rises, solute molecules gain energy and become ionised. As a result, as temperature rises, so does ionisation.
The dielectric constant of the fluid affects its ability to ionise. The solvent's ability to ionise more strongly and to a greater degree increases with a higher value of the dielectric constant.

Therefore, only current doesn’t effect the degree of ionization.

Option ‘D’ is correct

Note: Weak electrolytes experience a reduction or suppression in the degree of ionisation in the presence of common ions, as is known from the common ion effect rule. In other words, the common ion effect causes weak electrolytes to ionise to a lesser extent. Ionization takes place in weak electrolytes to a small degree. As a result, the unionised electrolyte and the ions created in the solution will be in equilibrium.
