Questions and Answers

What is a conjugate acid?

  • A base with a hydrogen ion added to it (correct)
  • An acid that has lost a hydrogen ion
  • A base that has gained a proton
  • A compound that can receive a proton
  • According to the Brønsted–Lowry theory, what is considered an acid?

  • Any compound that can give a proton to another compound (correct)
  • Any compound that can accept an electron
  • Any compound that can receive a proton from another compound
  • Any compound that can donate an electron
  • What is a conjugate base?

  • A substance formed by the removal of a proton from an acid (correct)
  • A base that has lost a hydrogen ion
  • A compound that can give a proton to another compound

    Study Notes

    Acid-Base Theory

    • A conjugate acid is the species that forms when a base accepts a proton (H+).
    • According to the Brønsted–Lowry theory, an acid is a species that donates a proton (H+).
    • A conjugate base is the species that forms when an acid donates a proton (H+).
    • A conjugate base of an acid can itself be acidic because it can still donate a proton, albeit less readily than the original acid.
    • In the context of the Brønsted–Lowry theory, a proton refers to a hydrogen ion (H+), which is a positively charged ion.
