The conduction of electricity through the electroly solution is due to

Options

A. Movement of molecules of electrolyte
B. Movement of ions of electrolyte
C. Movement of separate atoms
D. Movement of particles of the solvent

Answer

**Step-by-Step Text Solution:**

1. **Understanding Electrolytic Solutions**: An electrolytic solution is formed when an electrolyte (a substance that dissociates into ions when dissolved in a solvent) is dissolved in a solvent, typically water. This process allows the solution to conduct electricity.

2. **Movement of Ions**: The conduction of electricity in an electrolytic solution primarily occurs due to the movement of ions. When an electric field is applied, positive ions (cations) move towards the negative electrode (cathode), and negative ions (anions) move towards the positive electrode (anode).

3. **Role of Electrolyte**: The electrolyte dissociates into its constituent ions in the solution. For example, when sodium chloride (NaCl) is dissolved in water, it separates into Na⁺ and Cl⁻ ions. These ions are responsible for the conduction of electricity.

4. **Conductivity and Temperature**: The conductivity of an electrolytic solution is a temperature-dependent phenomenon. As the temperature increases, the mobility of the ions also increases, leading to higher conductivity.

5. **Resistance in Electrolytic Solutions**: While ions facilitate conduction, the solution also has resistance due to inter-ionic forces. These forces can hinder the movement of ions, affecting the overall conductivity of the solution.

6. **Conclusion**: In summary, the conduction of electricity through an electrolytic solution is primarily due to the movement of ions of the electrolyte, which allows for the flow of electric current.
