1. What is Degree of Dissociation?

Definition: The degree of dissociation (α) is the fraction of original solute molecules that have dissociated in solution.

Purpose: This calculator determines the degree of dissociation for one base when you know its dissociation constant and the degree of dissociation of another base.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \alpha_1 \) — Degree of dissociation of base 1
• \( \alpha_2 \) — Degree of dissociation of base 2
• \( K_{b1} \) — Dissociation constant of base 1
• \( K_{b2} \) — Dissociation constant of base 2

Explanation: The formula relates the dissociation degrees of two bases through the square root of the ratio of their dissociation constants.

3. Importance of Degree of Dissociation

Details: Knowing the degree of dissociation helps predict the strength of bases in solution and their chemical behavior.

4. Using the Calculator

Tips: Enter the known degree of dissociation (0-1), and both dissociation constants (must be > 0). The result will be between 0 and 1.

5. Frequently Asked Questions (FAQ)

Q1: What is the range for degree of dissociation?
A: It ranges from 0 (no dissociation) to 1 (complete dissociation).

Q2: How are dissociation constants determined?
A: They are experimentally determined values that measure base strength.

Q3: Can the result exceed 1?
A: The calculator caps results at 1, though theoretically the formula might give higher values for very strong bases.

Q4: What units are used for dissociation constants?
A: The units cancel out in the ratio, so any consistent units can be used.

Q5: Does temperature affect this calculation?
A: Yes, since dissociation constants are temperature-dependent.
