If the current is passed into the solution of the electrolyte

Options

A. anions move towards anode, cations towards cathode
B. anions and cations both move towards anode
C. anions move towards cathode cations towards anode
D. no movement of ions takes place

Explanation

### Step-by-Step Solution:

1. **Understanding Electrolysis**: Electrolysis is a process that uses an electric current to drive a chemical reaction. In this process, an electrolyte solution is decomposed into its constituent ions.

2. **Setting Up the Electrolysis Apparatus**: In a typical electrolysis setup, there are two electrodes: the anode (positive electrode) and the cathode (negative electrode). These electrodes are immersed in an electrolyte solution.

3. **Identifying the Movement of Ions**: When an electric current is passed through the electrolyte:
- **Anions (negatively charged ions)** move towards the anode because opposite charges attract.
- **Cations (positively charged ions)** move towards the cathode for the same reason.

4. **Analyzing the Options Given**: Based on the movement of ions:
- Option 1 states that "anions move towards anode and cations move towards cathode." This is correct.
- Option 2 states that "anions and cathode both move towards anode." This is incorrect because the cathode does not move; it is where cations are attracted.
- Option 3 states that "cations towards cathode." This is incomplete and misleading as it does not mention the movement of anions.
- Option 4 states "no movement of ions takes place." This is incorrect as ions definitely move during electrolysis.

5. **Conclusion**: The correct answer is that anions move towards the anode and cations move towards the cathode.

### Final Answer:
The correct statement is: **Anions move towards the anode and cations move towards the cathode.**
