1. What is Equivalent Conductance given Normality?

Definition: Equivalent conductance is defined as the conducting power of all the ions produced by one gram of an electrolyte in the given solution.

Purpose: This calculator helps determine the equivalent conductance based on specific conductance and normality of the solution.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \Lambda_{eq} \) — Equivalent conductance (S·m²/Eq)
• \( K \) — Specific conductance (S/m)
• \( N \) — Normality (mol/m³)

Explanation: The specific conductance is multiplied by the ratio of 1000 to normality to obtain the equivalent conductance.

3. Importance of Equivalent Conductance

Details: Equivalent conductance is crucial in electrochemistry for understanding ionic mobility and solution conductivity. It helps compare the conducting power of different electrolytes.

4. Using the Calculator

Tips: Enter the specific conductance in S/m and normality in mol/m³. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between specific and equivalent conductance?
A: Specific conductance measures conductivity per unit volume, while equivalent conductance measures conductivity per gram equivalent of electrolyte.

Q2: Why is 1000 used in the formula?
A: The factor 1000 converts between different units (mol/L to mol/m³) in the normality calculation.

Q3: What are typical values for specific conductance?
A: Values range widely: from ~0.01 S/m for weak electrolytes to ~10 S/m for strong electrolytes in concentrated solutions.

Q4: How does temperature affect these measurements?
A: Conductance increases with temperature (typically ~2% per °C), so measurements should specify temperature conditions.

Q5: Can this calculator be used for any electrolyte?
A: Yes, it works for all electrolytes, but interpretation of results may differ for strong vs. weak electrolytes.
