Is there a difference between the Brønsted and conjugated acids and bases? How do you tell them apart?

Conjugate Acids and bases describe the relationships between bronsted acids and bases. Bronsted acids donate protons and Bronsted bases act as proton acceptors. Protons are equivalent to H+, so think of the conjugate base to every bronsted acid as the molecule minus one H+ ion. HCl is an acid and Cl- is the conjugate base when HCl(aq) dissociates in water, it forms Cl- as well as H3O+ . Cl- can act as a proton acceptor (Bronsted base) This reaction in fact involves two conjugate pairs. HCl with Cl- as the conjugate base and H2O with the conjugate acid H3O+ (which can donate a proton).

Much Joy,
