In which solvent does sodium chloride and sugar dissolves?

Options

A. Naphthalene
B. Water
C. Anthracene
D. All of these

Answer

To determine the solvent in which sodium chloride (NaCl) and sugar (C6H12O6) dissolve, we can analyze the properties of both the solute (sodium chloride and sugar) and the potential solvents.

### Step-by-Step Solution:

1. **Identify the Solutes**:
- Sodium chloride (NaCl) is an ionic compound.
- Sugar (C6H12O6) is a covalent compound (specifically, it is glucose or sucrose).

2. **Consider the Solvent Options**:
- The question suggests different solvents, including naphthalene and water.
- Naphthalene is a solid at room temperature, while water is a liquid.

3. **Analyze Naphthalene**:
- Naphthalene is a non-polar solvent and is solid at room temperature.
- Solid solutes like sodium chloride and sugar do not dissolve well in solid solvents. Therefore, naphthalene is not a suitable solvent for either sodium chloride or sugar.

4. **Analyze Water**:
- Water is a polar solvent and is known for its ability to dissolve many ionic and polar substances.
- Sodium chloride, being an ionic compound, dissociates into Na⁺ and Cl⁻ ions in water.
- Sugar, being polar, also dissolves well in water due to hydrogen bonding.

5. **Conclusion**:
- Both sodium chloride and sugar dissolve in water, making it the correct solvent for both substances.

### Final Answer:
Sodium chloride and sugar dissolve in **water**.
