Questions and Answers

Which of the following is a correct definition of an acid?

  • An acid is a molecule that accepts electrons
  • An acid is a proton donor (correct)
  • An acid is a molecule that does not donate protons
  • An acid is a proton acceptor
  • Which of the following is true about strong acids?

  • They do not dissociate at all
  • They only dissociate in the presence of a base
  • They dissociate totally (correct)
  • They dissociate partially
  • Which of the following is a correct statement about lactic acid?

  • It does not dissociate at all
  • It is a weak acid and its anion is a base (correct)
  • It is a strong acid
  • Its anion is not a base
  • Study Notes

    • Lowry and Brønsted definitions of acid and base are relevant to biological systems.
    • An acid is a proton donor and a base is a proton acceptor.
    • Strong acids, like HCl and H2SO4, dissociate totally.
    • OH- ion is a base because it accepts a proton.
    • Neutralization occurs when a strong acid and OH- are combined.
    • Anions produced by strong acids are not bases.
    • Organic acids, like lactic acid, dissociate partially.
    • Lactic acid is a weak acid and its anion is a base.
    • Ammonium ion is an acid and ammonia is a conjugate base.
    • Phosphoric acid and its derivatives can act as both acids and bases.
