Which one of the following solution will highest conductivity ?

Options

A. `(0.1M CH_(3)COOH)`
B. `(0.1M NaC1)`
C. `(0.1M KNO_(3)`
D. `(0.1M HC1)`

Explanation

To determine which solution has the highest conductivity, we need to understand the concept of conductivity in solutions. Conductivity is the ability of a solution to conduct electricity, which primarily depends on the number of ions present in the solution. The more ions that are available to move and carry charge, the higher the conductivity.

### Step-by-Step Solution:

1. **Understanding Conductivity**:
- Conductivity is related to the presence of ions in a solution. The more ions present, the higher the conductivity.

2. **Identifying the Solutions**:
- Let's consider the solutions provided in the options:
- Option 1: Acetic Acid (CH₃COOH)
- Option 2: Sodium Chloride (NaCl)
- Option 3: Potassium Nitrate (KNO₃)
- Option 4: Hydrochloric Acid (HCl)

3. **Analyzing Acetic Acid**:
- Acetic acid is a weak acid and does not dissociate completely in solution. Therefore, it produces fewer ions compared to strong acids or salts.
- Conclusion: Low conductivity.

4. **Analyzing Sodium Chloride (NaCl)**:
- NaCl is a strong electrolyte and dissociates completely into Na⁺ and Cl⁻ ions in solution.
- Conclusion: Moderate conductivity.

5. **Analyzing Potassium Nitrate (KNO₃)**:
- KNO₃ is also a strong electrolyte and dissociates completely into K⁺ and NO₃⁻ ions in solution.
- Conclusion: Moderate conductivity, similar to NaCl.

6. **Analyzing Hydrochloric Acid (HCl)**:
- HCl is a strong acid and dissociates completely into H⁺ and Cl⁻ ions in solution.
- Conclusion: High conductivity due to the presence of a large number of ions.

7. **Comparing Conductivities**:
- Among the options:
- Acetic Acid has the lowest conductivity.
- NaCl and KNO₃ have moderate conductivity.
- HCl has the highest conductivity due to complete dissociation.

8. **Final Conclusion**:
- The solution with the highest conductivity is Hydrochloric Acid (HCl).

### Final Answer:
**Hydrochloric Acid (HCl) has the highest conductivity among the given options.**
