1. What is Degree of Dissociation?

Definition: The Degree of Dissociation is the extent of generating current carrying free ions, which are dissociated from the fraction of solute at a given concentration.

Purpose: It measures how much a compound separates into its constituent ions or molecules.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \alpha \) — Degree of Dissociation
• \( d \) — Equilibrium Vapour Density
• \( D \) — Initial Vapour Density

Explanation: The formula calculates the fraction of molecules that dissociate when the number of moles of products at equilibrium is half.

3. Importance of Degree of Dissociation

Details: Understanding dissociation is crucial for studying chemical equilibria, reaction rates, and electrolyte behavior in solutions.

4. Using the Calculator

Tips: Enter the equilibrium vapour density (d) and initial vapour density (D). The calculator will determine the degree of dissociation.

5. Frequently Asked Questions (FAQ)

Q1: What does a degree of dissociation of 1 mean?
A: A value of 1 indicates complete dissociation of all molecules into ions or smaller components.

Q2: Can the degree of dissociation be negative?
A: No, it should be between 0 (no dissociation) and 1 (complete dissociation). Negative values indicate calculation errors.

Q3: How does temperature affect degree of dissociation?
A: Generally, dissociation increases with temperature as more energy is available to break bonds.

Q4: What's the difference between d and D?
A: Initial vapour density (D) is before dissociation occurs, while equilibrium vapour density (d) is measured after equilibrium is established.

Q5: Why is the factor 2 included in the formula?
A: The factor accounts for the stoichiometry when the number of moles of products at equilibrium is half the initial amount.
