Define conductivity and molar conductivity for the solution of an electrolyte. How do they vary when the concentration of electrolyte in the solution increases ?

Explanation

Conductivity : Conductivity is defined as conductance of one centimetre cube of the solution of an electrolyte. It is denoted by `ĸ`. The inverse of resistivity is called conductivity.
Molar conductivity : Molar conductivity is the conducting power of all the ions produced by dissolving one mole of electrolyte in solution. It is denoted by `wedge_(m)`.
Variation of `ĸ and wedge_(m)` with concentration of electrolyte
The conductivity `(ĸ)` of an electrolyte solution increases with increase in concentration because the ions per unit volume increases.
The molar conductivity of the solution of an electrolyte decreases with increase in the concentration of an electrolyte.
