1. What is Specific Conductance?

Specific conductance (κ) is a measure of the ability of an electrolyte solution to conduct electricity, normalized by concentration. It is calculated as the ratio of conductivity (σ) to molar concentration (c).

2. How Does the Calculator Work?

The calculator uses the specific conductance formula:

Where:

• \( \kappa \) — Specific conductance (S·m²/mol)
• \( \sigma \) — Conductivity (S/m)
• \( c \) — Molar concentration (mol/m³)

Explanation: This formula calculates the specific conductance by dividing the measured conductivity by the molar concentration of the solution.

3. Importance of Specific Conductance

Details: Specific conductance is important in electrochemistry and analytical chemistry for characterizing electrolyte solutions and understanding ionic mobility in solutions.

4. Using the Calculator

Tips: Enter conductivity in S/m and concentration in mol/m³. Both values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between conductivity and specific conductance?
A: Conductivity (σ) measures the overall ability of a solution to conduct electricity, while specific conductance (κ) normalizes this by concentration to allow comparison between different solutions.

Q2: What are typical units for specific conductance?
A: Specific conductance is typically expressed in S·m²/mol in SI units.

Q3: When is specific conductance measurement important?
A: It's crucial in electrochemistry, water quality testing, and studying ionic solutions where concentration effects need to be accounted for.

Q4: How does temperature affect specific conductance?
A: Like conductivity, specific conductance increases with temperature. Measurements are often standardized to 25°C for comparison.

Q5: Can this calculator be used for any electrolyte solution?
A: Yes, the formula applies to all electrolyte solutions, though the actual values will depend on the specific ions present and their concentrations.
