consider this reaction: koh + hbr → kbr + h₂o\nwhich is the acid in this reaction?\no koh\no hbr\no kbr\no h₂o

Brief Explanations:

In an acid - base reaction, an acid donates a proton (H⁺). HBr donates a proton to form Br⁻ and combines with the OH⁻ from KOH to form water. 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⁺ and OH⁻.

Answer:

B. HBr
