The current flow through electrolyte is due to the movement of:

Options

A. Holes
B. Ions
C. Electrons
D. None of these

Explanation

**Step-by-Step Solution:**

1. **Understanding Electrolytes:**
- An electrolyte is a substance that dissociates into ions when dissolved in water. For example, sodium chloride (NaCl) dissociates into sodium ions (Na⁺) and chloride ions (Cl⁻).

2. **Current Flow in Electrolytes:**
- The flow of electric current through an electrolyte occurs due to the movement of charged particles. In the case of electrolytes, these charged particles are ions.

3. **Role of Ions:**
- When an electric current is applied to an electrolyte solution, the positively charged ions (cations) move towards the negatively charged electrode (cathode), while negatively charged ions (anions) move towards the positively charged electrode (anode).

4. **Example of Ion Movement:**
- Taking the example of NaCl in an aqueous solution:
- NaCl → Na⁺ + Cl⁻
- When connected to a battery, Na⁺ ions migrate towards the cathode, and Cl⁻ ions migrate towards the anode.

5. **Conclusion:**
- Therefore, the current flow through an electrolyte is due to the movement of ions, not electrons or holes.

**Final Answer:**
The current flow through an electrolyte is due to the movement of ions.
