Final answer:
The ionization reaction for nitric acid (HNO3), a strong acid, is HNO3(aq) + H2O(l) → H3O+(aq) + NO3-(aq). For acetic acid (HC2H3O2), a weak acid, the reaction is HC2H3O2(aq) + H2O(l) ⇌ H3O+(aq) + C2H3O2-(aq). Strong acids dissociate completely, while weak acids partially dissociate.
Step-by-step explanation:
Ionisation Reactions of Acids in Water
To write the ionisation reactions of acids in water, we consider whether the acid is strong or weak. A strong acid dissociates completely in water, while a weak acid only partially dissociates. Below are the ionisation reactions for the given acids:
a. Nitric Acid (HNO3)
HNO3(aq) + H2O(l) → H3O+(aq) + NO3−(aq)
b. Acetic Acid (HC2H3O2)
HC2H3O2(aq) + H2O(l) ⇌ H3O+(aq) + C2H3O2−(aq)
Note that nitric acid is a strong acid and dissociates completely, indicated by the one-way arrow (→), whereas acetic acid is a weak acid and only partially dissociates, indicated by the equilibrium arrows (⇌).
