Answer:
The strength of an acid depends on the concentration of the hydronium ions (H3O+) present in the aqueous solution of an acid.
- Strong Acids
A strong acid vigorously ionises in aqueous solution completely thereby producing a high concentration of hydronium ions (H3O+).
Examples: HNO3, HCl, H2SO4
Reaction:
HCl + H2O ⇋ H3O+ + Cl−
- Weak Acids
Weak acids ionise only partially in aqueous solution to produce ions and molecules.
Examples: H2CO3, CH3COOH, HCOOH
Reaction:
CH3COOH + H2O ⇋ H+ + CH3COO−
