Which one of the following solutions will not conduct electricity?

Options

A. lemon juice
B. tap water
C. vinegar
D. vegetable oil

Answer

To determine which solution will not conduct electricity, we need to understand the concept of electrical conductivity in solutions. A solution conducts electricity when it contains ions that can move freely. Here’s a step-by-step analysis of the given options:

### Step-by-Step Solution:

1. **Understanding Conductivity**:
- Solutions conduct electricity when they contain ions. Ions are charged particles that result from the dissociation of substances in water.

2. **Analyzing Lemon Juice**:
- Lemon juice contains citric acid, which dissociates into citrate ions when dissolved in water.
- **Conclusion**: Lemon juice conducts electricity.

3. **Analyzing Tap Water**:
- Tap water often contains dissolved salts and minerals, which dissociate into ions.
- **Conclusion**: Tap water conducts electricity.

4. **Analyzing Vinegar**:
- Vinegar contains acetic acid, which dissociates into acetate ions in water.
- **Conclusion**: Vinegar conducts electricity.

5. **Analyzing Vegetable Oil**:
- Vegetable oil does not dissociate into ions when mixed with water. It remains as a non-polar substance and does not produce any ions.
- **Conclusion**: Vegetable oil does not conduct electricity.

### Final Answer:
The solution that will not conduct electricity is **Vegetable Oil**.
