Degree of Dissociation Formula:
From: | To: |
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.
The calculator uses the formula:
Where:
Explanation: The formula relates the dissociation degrees of two bases through the square root of the ratio of their dissociation constants.
Details: Knowing the degree of dissociation helps predict the strength of bases in solution and their chemical behavior.
Tips: Enter the known degree of dissociation (0-1), and both dissociation constants (must be > 0). The result will be between 0 and 1.
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.
