1. What is Dissociation Constant of Acid 1?

Definition: The Dissociation Constant of Acid 1 (Ka₁) measures the extent to which acid 1 dissociates in solution. It's calculated based on the dissociation constant of acid 2 and the degrees of dissociation of both acids.

Purpose: This calculation helps chemists compare the relative strengths of two acids and understand their behavior in solution.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ Ka_1 = (Ka_2) \times \left(\frac{\alpha_1}{\alpha_2}\right)^2 \]

Where:

\( Ka_1 \) — Dissociation constant of acid 1
\( Ka_2 \) — Dissociation constant of acid 2
\( \alpha_1 \) — Degree of dissociation of acid 1 (0 to 1)
\( \alpha_2 \) — Degree of dissociation of acid 2 (0 to 1)

Explanation: The formula relates the dissociation constants of two acids through their degrees of dissociation, showing how much more or less one acid dissociates compared to another.

3. Importance of Acid Dissociation Constants

Details: Knowing dissociation constants helps predict acid strength, pH of solutions, and reaction outcomes in chemical processes.

4. Using the Calculator

Tips: Enter the dissociation constant of acid 2, and the degrees of dissociation for both acids (values between 0 and 1). All values must be positive.

5. Frequently Asked Questions (FAQ)

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

Q2: How do I find the degree of dissociation?
A: It can be determined experimentally by measuring conductivity or pH of the solution.

Q3: What units does Ka use?
A: Dissociation constants are dimensionless as they represent equilibrium concentrations.

Q4: Why is the ratio squared in the formula?
A: The square accounts for the quadratic relationship between dissociation constant and degree of dissociation.

Q5: Can I compare strong and weak acids with this?
A: Yes, as long as both acids are weak (α significantly less than 1), this comparison is valid.
