Acid and Base Conjugate Pairs

Front

What is a conjugate acid?

Back

A conjugate acid is the species formed when a base gains a proton (H+).

Front

What is a conjugate base?

Back

A conjugate base is the species that remains after an acid donates a proton (H+).

Front

What is the Bronsted-Lowry theory of acids and bases?

Back

The Bronsted-Lowry theory defines acids as proton donors and bases as proton acceptors.
