Conductivity Formula:
From: | To: |
Definition: This calculator determines the specific conductance of a solution based on its molar conductivity and molar volume.
Purpose: It helps chemists and researchers calculate the conductivity of electrolyte solutions for various applications.
The calculator uses the formula:
Where:
Explanation: The specific conductance is obtained by dividing the molar conductivity by the molar volume of the solution.
Details: Conductivity measurements are crucial for understanding electrolyte behavior, water quality assessment, and industrial process control.
Tips: Enter the solution molar conductivity (in S·m²/mol) and molar volume (default 0.0224 m³/mol for ideal gases at STP). All values must be > 0.
Q1: What is typical molar volume at STP?
A: For ideal gases, the molar volume at standard temperature and pressure (STP) is 0.0224 m³/mol.
Q2: How does temperature affect conductivity?
A: Conductivity generally increases with temperature as ion mobility increases.
Q3: What are typical molar conductivity values?
A: Values vary by electrolyte but range from 0.01 to 0.15 S·m²/mol for common aqueous solutions.
Q4: Can this calculator be used for non-ideal solutions?
A: Yes, but you must use the actual molar volume of your specific solution.
Q5: What units should I use for accurate results?
A: Ensure consistent SI units: S·m²/mol for molar conductivity and m³/mol for molar volume.
