Which one is an electrolyte ?

Options

A. `CH_(4)`
B. `C_(6)H_(12)O_(6)`
C. `NaCl`
D. `N_(2)C_(4)`

Answer

**Step-by-Step Solution:**

1. **Understanding the Definition of an Electrolyte:**
An electrolyte is defined as a substance that dissociates into ions when dissolved in water. This dissociation allows the solution to conduct electricity.

2. **Identifying Examples of Electrolytes:**
Common examples of electrolytes include salts, acids, and bases. For instance, sodium chloride (NaCl) is a well-known electrolyte.

3. **Analyzing the Given Substances:**
In the context of the question, we need to evaluate the substances provided (though not explicitly listed here) to determine which one is an electrolyte.

4. **Evaluating Sodium Chloride (NaCl):**
When NaCl is dissolved in water, it dissociates into sodium ions (Na⁺) and chloride ions (Cl⁻). This process confirms that NaCl is indeed an electrolyte.

5. **Comparing with Other Substances:**
Other substances mentioned, such as CH₄ (methane) and glucose, do not dissociate into ions in solution. Therefore, they are not electrolytes.

6. **Conclusion:**
Based on the analysis, NaCl is the substance that qualifies as an electrolyte because it dissociates into ions in an aqueous solution and can conduct electricity.

**Final Answer:**
Sodium chloride (NaCl) is an electrolyte.
