Question
Identify acid, base, conjugate acid, and conjugate base in the following reaction.
CH3COOH(aq) + NH3(g) → CH3COO―(aq) + NH4+(aq)
Solution
In the given reaction:
CH3COOH(aq) + NH3(g) → CH3COO−(aq) + NH4+(aq)
-
Acid: The acid is the species that donates a proton (H+ ion). In this reaction, CH3COOH (acetic acid) is donating a proton to NH3, so CH3COOH is the acid.
-
Base: The base is the species that accepts a proton. In this reaction, NH3 (ammonia) is accepting a proton from CH3COOH, so NH3 is the base.
-
Conjugate Acid: The conjugate acid is the species that is formed after the base accepts a proton. In this reaction, after NH3 accepts a proton, it becomes NH4+ (ammonium ion). So, NH4+ is the conjugate acid.
-
Conjugate Base: The conjugate base is the species that is formed after the acid donates a proton. In this reaction, after CH3COOH donates a proton, it becomes CH3COO− (acetate ion). So, CH3COO− is the conjugate base.
