Sodium chloride is ..........

Options

A. strong electrolyte
B. weak electrolyte
C. non-electrolyte
D. None of these

Explanation

**Step-by-Step Solution:**

1. **Understanding Sodium Chloride**: Sodium chloride (NaCl) is commonly known as table salt. It is an ionic compound formed from sodium (Na⁺) and chloride (Cl⁻) ions.

2. **Definition of Electrolytes**: An electrolyte is a substance that dissociates into ions when dissolved in water. This dissociation allows the solution to conduct electricity.

3. **Classification of Electrolytes**: Electrolytes can be classified into two categories: strong electrolytes and weak electrolytes.

- **Strong Electrolytes**: These substances completely dissociate into their ions in solution. For example, sodium chloride dissociates fully into Na⁺ and Cl⁻ ions when dissolved in water.

- **Weak Electrolytes**: These substances only partially dissociate into ions in solution.

4. **Sodium Chloride as a Strong Electrolyte**: Since sodium chloride is a salt, it is classified as a strong electrolyte. When NaCl is dissolved in water, it dissociates completely into sodium ions (Na⁺) and chloride ions (Cl⁻), allowing the solution to conduct electricity effectively.

5. **Conclusion**: Therefore, sodium chloride is a strong electrolyte because it completely dissociates into its constituent ions in aqueous solution.

**Final Answer**: Sodium chloride is a strong electrolyte.
