Which of the following is a weak acid? A) B(OH)₃ B) HI C) B(OH)₄^- D) B₂(O₂)₂(OH)₄^2-

Question

Quizplus · Accepted Answer

B(OH)3 (boric acid) is a weak acid because it only partially dissociates in water, producing a low concentration of H+ ions. HI (hydroiodic acid) is a strong acid, and B(OH)4- (borate ion) and H2SO4 (sulfuric acid) are both very strong, completely dissociating in water. The long compound in choice D is not recognizable as a known acid and therefore cannot be classified.
