The conduction of electricity through the electrolyte 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

To solve the question regarding the conduction of electricity through an electrolyte solution, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Electrolytes**:
- Electrolytes are substances that dissociate into ions when dissolved in a solvent (usually water). This dissociation is crucial for the conduction of electricity.

2. **Identifying Charged Particles**:
- The conduction of electricity requires the movement of charged particles. In the case of electrolytes, these charged particles are ions, which can be either positively charged (cations) or negatively charged (anions).

3. **Analyzing the Options**:
- **Option 1**: Movement of molecules of electrolyte - This is incorrect because neutral molecules do not carry charge and therefore cannot conduct electricity.
- **Option 2**: Movement of ions of electrolyte - This is correct. The movement of ions (both cations and anions) in the solution allows for the conduction of electricity.
- **Option 3**: Movement of separate atoms - This is incorrect as individual atoms do not carry charge in the context of electrolyte solutions.
- **Option 4**: Movement of particles of the solvent - This is also incorrect since the solvent particles (like water) do not carry charge and do not contribute to electrical conduction.

4. **Conclusion**:
- Based on the analysis of the options, the correct answer is **Option 2: Movement of ions of electrolyte**. This is the mechanism by which electricity is conducted in an electrolyte solution.

### Final Answer:
The conduction of electricity through the electrolyte solution is due to the **movement of ions of electrolyte**.
