Answer:

d) NH4F

Step-by-step explanation:

Hello,

In this case, the base resulting from mixing a weak acid and a weak base is d) NH4F since ammonium hydroxide is a wear base and hydrofluoric acid is a weak acid.

Ammonium hydroxide is a weak base since it is not completely ionized in ammonium and hydroxyl ions:

$NH_4OH\rightarrow NH_4^++OH^-$

Moreover, hydrofluoric acid is a weak acid since it is not completely ionized in hydrogen and fluoride ions:

$HF\rightleftharpoons H^++F^-$

For the both of the substances, the limit is established by the basic and the acid dissociation constant respectively.

Regards.
