Base: A base is a substance that can accept protons (H+) in a chemical reaction.
Conjugate Base: The conjugate base of an acid is formed when the acid loses a proton. In this case, the conjugate base of HOBr would be OBrโป, as it is formed after HOBr donates its proton.
Acid: An acid is a substance that can donate protons (H+) in a chemical reaction.
