SI Unit for Conductivity of a Solution
Explanation:
Conductivity is a measure of how well a substance conducts an electric current. It is the reciprocal of resistivity and is expressed in Siemens per meter (S m^–1).
Conductivity:
- Conductivity is a property of a substance that determines its ability to conduct electric current.
- It depends on the concentration of ions in the solution and their mobility.
- Solutions with higher ion concentrations and higher ion mobilities have higher conductivity values.
Cell Constant:
- The cell constant is a conversion factor that relates the resistance of a conductivity cell to the conductivity of the solution.
- It is usually determined by measuring the resistance of the cell containing a solution whose conductivity is already known.
Measurement of Cell Constant:
- KCl solutions are commonly used to determine the cell constant because their conductivity is known accurately at various concentrations and temperatures.
- The resistance of the cell filled with a 0.1 M KCl solution is measured and found to be 200 Ohm.
- Similarly, the resistance of the same cell when filled with a 0.02 M KCl solution is measured and found to be 420 Ohm.
Relationship between Conductivity and Resistance:
- The resistance of a conductivity cell is inversely proportional to the conductivity of the solution.
- As the concentration of KCl decreases from 0.1 M to 0.02 M, the conductivity decreases, and hence, the resistance increases.
SI Unit of Conductivity:
- The SI unit for conductivity is Siemens per meter (S m^–1).
- It represents the conductance of a substance per unit length.
- In this case, the conductivity of the 0.1 M KCl solution is given as 1.29 S m^–1, which means that the solution can conduct 1.29 Siemens of electric current per meter length.
Conclusion:
- The SI unit for conductivity of a solution is S m^–1 (Option A).
- It is a measure of the substance's ability to conduct electric current and is determined by the resistance of the conductivity cell filled with a known concentration of KCl solution.
