We have to determine which of the species make up a base-conjugate acid pair.

Conjugate acids and bases are a part of the Brønsted-Lowry acid-base theory.

  • This theory is based on the transfer of protons.
  • A base is a proton acceptor.
  • A base gains a positive charge by the gain of a proton.
  • The specie formed after the gain of a proton by a base is called its conjugate acid.
