Bronsted acid

Why is HBr a bronsted acid?

[Ashish Verma 2I]

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

[josephperez_2C]

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

[Manas_Varma_4B]

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

[timschaeffer Dis 1J]

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.

[Eva Zhao 4I]

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

[alexfwang3g]

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

[lauraxie2e]

It completely dissociates to lose one H

[Hailey Kim 4G]

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-.

[Anvi Brahmbhatt 4A]

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