Conjugate acid-base pairs (AP chem)

Front

What is a conjugate acid?

Back

A conjugate acid is the species formed when a base accepts a hydrogen ion (H+).

Front

What is a conjugate base?

Back

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

Front

What do conjugate acid-base pairs consist of?

Back

Conjugate acid-base pairs consist of two species that differ by one hydrogen ion (H+).
