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 helps quantify how much a compound breaks down into its constituent parts in a solution.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ \alpha = \frac{D - d}{d \times (n - 1)} \]

Where:

\( \alpha \) — Degree of Dissociation
\( D \) — Initial Vapour Density
\( d \) — Equilibrium Vapour Density
\( n \) — Number of Moles

Explanation: The formula compares the initial and equilibrium vapour densities, normalized by the number of moles to determine the dissociation fraction.

3. Importance of Degree of Dissociation

Details: Understanding dissociation is crucial for predicting reaction behavior, equilibrium concentrations, and solution properties in chemistry.

4. Using the Calculator

Tips: Enter the initial vapour density, equilibrium vapour density, and number of moles. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is vapour density?
A: Vapour density is the density of a vapour relative to that of hydrogen under the same conditions.

Q2: Why do we need number of moles in the calculation?
A: The number of moles accounts for the stoichiometry of the dissociation reaction.

Q3: What does a degree of dissociation of 1 mean?
A: A value of 1 indicates complete dissociation of the compound into its ions.

Q4: Can the degree of dissociation exceed 1?
A: No, it's a fraction between 0 (no dissociation) and 1 (complete dissociation).

Q5: How does temperature affect dissociation?
A: Generally, dissociation increases with temperature as bonds are more easily broken.
