Answer:
the amount of ionization that occurs in solution
Step-by-step explanation:
An acid is a substance that interacts with water to produce excess hydroxonium ions, H₃0⁺ in an aqueous solution.
The ionization of acids in solution determines the strength of the acid.
A strong acid is one that ionizes almost completely in solutions and a weak acid is one that ionizes slightly and sets up an equilibrium.
HCl + H₂0 → H₃0⁺ + Cl⁻ this is the ionization of strong acid
CH₃COOH + H₂O ⇄ H₃0⁺ + CH₃COO⁻ ionization of a weak acid
