Household ammonia solution (primarily

NH_3

) accidentally spills onto a countertop that was just cleaned with vinegar (aqueous

CH_3COOH

). Which net ionic equation represents the dominant acid–base process that occurs on the surface? (a)

NH_4^{+}+CH_3COO^{-}\rightarrow NH_3+CH_3COOH

(b) No reaction occurs because both substances are weak and remain unreactive. (c)

NH_3+CH_3COOH\rightarrow NH_4^{+}+CH_3COO^{-}

(d)

NH_3+CH_3COOH\rightarrow NH_4^{+}+CH_3COOH
