Question

if the ions size is decrease in a solution​

Answer 1

If the ions decrease in a solution then conductance decreases so option (1) is correct.

How the conductance decreases:

• The conductance of a solution increases as the number of ions in the solution increases.

• The solvation, or the number of solvent molecules attracted to the ion, increases as the size of the ion decreases. As a result of the ion's inability to move quicker, the solution's conductance diminishes.

• The concentration of the electrolyte affects conductivity. Dilution reduces the number of ions per unit volume carrying the current, hence conductivity constantly drops as concentration lowers.

• The degree of dissociation, which increases the number of ions, causes molar conductivity to increase with dilution.
