Ammonia and fluoride ion are weak acids due to limited ionization in water, similar to hydrofluoric acid. Basicity and donor abilities influence their weak acid characteristics.
Ammonia and fluoride ion are weak acids due to their limited ionization in water.
This is exemplified by the weak acid hydrofluoric acid (HF), which has a low pKa value and ionizes to a small extent. The basicity and donor abilities of ammonia and fluoride ion play a role in their weak acid properties.
