1. What is a Dissociation Equation?

A dissociation equation represents the separation of a compound into its constituent ions when dissolved in a solution. For acids, it shows the release of hydrogen ions (H⁺), while for bases, it shows the release of hydroxide ions (OH⁻).

2. How Does the Calculator Work?

The calculator processes the dissociation equation:

Where:

• \( HA \) — The acid formula (e.g., HCl, CH₃COOH)
• \( H^+ \) — Hydrogen ion released
• \( A^- \) — Conjugate base formed

Explanation: The equation shows the reversible dissociation of an acid into its ions, with the extent of dissociation determined by the acid's strength and concentration.

3. Importance of Dissociation Equations

Details: Understanding dissociation equations is crucial for predicting acid-base behavior, calculating pH, determining buffer capacity, and understanding electrolyte properties in solutions.

4. Using the Calculator

Tips: Enter the acid formula (HA) and the complete dissociation equation. The calculator will process and display the formatted result showing the dissociation process.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between strong and weak acid dissociation?
A: Strong acids dissociate completely (→), while weak acids dissociate partially (⇌) and have equilibrium constants (Kₐ) less than 1.

Q2: How do polyprotic acids differ in dissociation?
A: Polyprotic acids have multiple dissociation steps (e.g., H₂SO₄ → H⁺ + HSO₄⁻ followed by HSO₄⁻ ⇌ H⁺ + SO₄²⁻), each with its own equilibrium constant.

Q3: What factors affect acid dissociation?
A: Temperature, concentration, solvent properties, and the presence of other ions can all influence the extent of acid dissociation.

Q4: How is base dissociation represented?
A: Base dissociation follows B + H₂O ⇌ BH⁺ + OH⁻, where B is the base and BH⁺ is its conjugate acid.

Q5: What is the relationship between Kₐ and pKₐ?
A: pKₐ = -log₁₀(Kₐ), where Kₐ is the acid dissociation constant. Lower pKₐ values indicate stronger acids.
