Question 9 Which conjugate acid-base pair is incorrectly matched? A. HCl and Cl- B. H2CO3 and CO32- C. H2O and OH- D. HCN and CN-
Conjugate acid and Conjugate bases are the acids and bases that loose or gain electrons. Conjugate acid of a base is formed when the base accepts a proton of hydrogen ion. Conjugate base is formed when an acid looses a hydrogen ion when it is dissolved into its ions.
