Answer

Brief Explanations:

In an acid - base reaction, an acid is a substance that donates a proton (H⁺). HBr donates a proton in this reaction. KOH is a base as it donates OH⁻. KBr is a salt formed from the reaction of the acid and base, and H₂O is the product of the reaction between H⁺ from the acid and OH⁻ from the base.
