vovangra [49]

Answer:

The relative conjugate acids and bases are listed below:

CH3NH2 → CH3NH3+

H2SO3→ HSO3-

NH3→ NH4+

Explanation:

In a Brønsted-Lowry acid-base reaction, a conjugate acid is the species resulting from a base accepting a proton; likewise, a conjugate base is the species formed after an acid has donated a hydrogen atom (proton).

To this end:

  • HSO3- is the conjugate acid of H2SO3 i.e sulfuric acid has lost a proton (H+)
  • NH4+ is the conjugate acid of NH3 i.e the base ammonia has gained a proton (H+)
  • OH- is the conjugate base of H20
  • CH3NH3+ is the conjugate base of the base CH3NH2 methylamine
