1. What is Concentration of Electrolyte given Fugacity?

Definition: This calculator determines the actual concentration of an electrolyte solution based on ionic activity and fugacity.

Purpose: It helps chemists and engineers calculate the effective concentration of ions in solution, accounting for non-ideal behavior.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( c \) — Actual concentration (mol/m³)
• \( a \) — Ionic activity (mol/kg)
• \( f \) — Fugacity (Pa)

Explanation: The square root of ionic activity is divided by the square of fugacity to account for non-ideal behavior in electrolyte solutions.

3. Importance of Electrolyte Concentration Calculation

Details: Accurate concentration calculations are crucial for predicting solution behavior, reaction rates, and electrochemical properties.

4. Using the Calculator

Tips: Enter the ionic activity in mol/kg and fugacity in Pascals. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is ionic activity?
A: Ionic activity is the effective concentration of ions in solution, accounting for interactions between charged particles.

Q2: What does fugacity represent?
A: Fugacity is a measure of a substance's tendency to escape from one phase to another, accounting for non-ideal gas behavior.

Q3: Why do we square the fugacity?
A: Squaring fugacity accounts for its effect on both the numerator and denominator in the equilibrium expression.

Q4: When would I need this calculation?
A: This is particularly important in electrochemical systems, battery research, and corrosion studies.

Q5: How precise should my inputs be?
A: For accurate results, measure ionic activity and fugacity with precision, typically to at least 3 significant figures.
