Which of these will act as a non-electrolyte?

Options

A. Liquid carbon tetrachloride
B. Acetic acid
C. Sodium hydroxide aqueous solution
D. Potassium chloride aqueous solution

Explanation

To determine which of the given substances acts as a non-electrolyte, we need to understand the definitions of electrolytes and non-electrolytes.

### Step-by-Step Solution:

1. **Define Non-Electrolyte**:
A non-electrolyte is a substance that does not dissociate into ions when dissolved in water (aqueous solution) or in a molten state.

2. **Identify the Substances**:
We need to consider the substances provided in the question. For this example, let's assume the substances are carbon tetrachloride (CCl₄), acetic acid (CH₃COOH), sodium hydroxide (NaOH), and potassium chloride (KCl).

3. **Analyze Each Substance**:
- **Carbon Tetrachloride (CCl₄)**:
- This compound does not dissociate into ions in aqueous solution. Therefore, it is classified as a non-electrolyte.
- **Acetic Acid (CH₃COOH)**:
- Acetic acid partially dissociates into ions (CH₃COO⁻ and H⁺) in solution. Thus, it is a weak electrolyte.
- **Sodium Hydroxide (NaOH)**:
- Sodium hydroxide completely dissociates into Na⁺ and OH⁻ ions in solution, making it a strong electrolyte.
- **Potassium Chloride (KCl)**:
- Potassium chloride also completely dissociates into K⁺ and Cl⁻ ions in solution, classifying it as a strong electrolyte.

4. **Conclusion**:
Among the substances analyzed, only carbon tetrachloride (CCl₄) does not dissociate into ions in an aqueous solution. Therefore, it is the only non-electrolyte.

### Final Answer:
**Carbon Tetrachloride (CCl₄) is the non-electrolyte.**
