Define conductivity and molar conductivity for the solution of an electrolyte. Discuss their variation with concentration.

Explanation

### Step-by-Step Text Solution:

**Step 1: Define Conductivity**
Conductivity (κ) is defined as the ability of an electrolytic solution to conduct electric current. It is the total conductance provided by the electrolytic solution present between two electrode plates. Mathematically, it can be expressed as:

\[ \kappa = \frac{G \cdot d}{A} \]
