Hypobromous acid has a pKa of 8.65 and is therefore only partially dissociated in water at pH 7. Wednesday, November 4, 3:00AM - 12:00PM ET, The Dissociation Constant of Hypobromous Acid.

At equilibrium, the dissociation constant can be expressed as follows: {eq}\begin{align}

HOBr is used as a bleach, an oxidizer, a deodorant, and a disinfectant, due to its ability to kill the cells of many pathogens. Therefore, it will partially dissociate in water as follows: {eq}HBrO\ \leftrightharpoons \ BrO^{-}\ +\ H^{+}\\[0.3 cm]
