Dissociation & Ionization
Type a formula (e.g., MgCl2, Na2SO4, Ca(OH)2, HCl, CH3COOH).
States like (aq), (s), (l), (g) are allowed and ignored for parsing.

Frequently Asked Questions
What is the difference between dissociation and ionization in water?
Dissociation separates ions that already exist in an ionic compound into hydrated ions in solution. Ionization forms ions from a molecular compound, such as an acid reacting with water to produce H3O+ and its conjugate base.
How does the calculator decide if an acid is strong or weak?
The tool uses built-in lists for common strong acids and weak acids. Strong acids are shown as essentially complete ionization, while weak acids are shown with an equilibrium arrow to indicate partial ionization.
Why is charge balance important for dissociation and ionization equations?
A valid set of ions must conserve total charge, so the sum of (stoichiometric count x ionic charge) across products should equal zero for a neutral solute. The calculator displays this charge accounting to verify the proposed ions.
Can I include states like (aq), (s), (l), or (g) in the input formula?
Yes. The calculator accepts common state symbols and ignores them for parsing, so you can enter formulas like MgCl2(aq) without changing the computed ions.
