HOBr is a weak acid known as hypobromous acid. It can donate a proton (H+) in a chemical reaction.
A base is a substance that can accept protons (H+) in a chemical reaction.
The conjugate base of an acid is formed when the acid loses a proton. In this case, the conjugate base of HOBr would be OBr⁻, as it is formed after HOBr donates its proton.
