Why is HBr a bronsted acid?

Because it donates a proton to become a stable anion (Br-)

It is a strong acid because it loses an H+. It's equation of dissociation is HBr(aq) -> H+(aq) + Br-(aq).

It's a strong acid because it completely disassociates by losing its one proton, H+.

You can tell that Hbr is especially strong because Br is a halogen, meaning that it already wants to shed a hydrogen proton so it can gain an electron and become isoelectric with krypton. Br also has a relatively low electronegativity compared to other halogens like fluorine, so it holds less tightly onto the hydrogen (which it already wants to get rid of). Both of these factors combine to result in a compound (HBr) that readily gives off a proton in solution and does not want to return to its original state, classifying it as a strong acid.

By definition, Bronsted acids are proton donors. HBr is a Bronsted acid because it can donate its H+, to which it would become Br-.

HBr is a proton giver and a lone pair/electron acceptor.

A Bronsted acid is a species that is capable of donating a proton. HBr classifies as a Bronsted acid because it donates a H+ to water (the Bronsted base). HBr donates its proton to become Br-.

HBr is a Bronsted acid because it donates an H+ proton.
