Chapter 15 - Aqueous Equilibria: Acids and Bases - Worked Example - Page 613: 8


(a) $HS^-$ and $HSe^-$(Stronger). (b) $I^-$ and $HTe^-$(Stronger). (c) $N{O_2}^-$(Stronger) and $N{O_3}^-$ . (d) $HS{O_3}^-$ and $HSe{O_3}^-$ (Stronger).

Work Step by Step

- To get the conjugate base of an acid, remove one hydrogen, and subtract 1 from the charge: Ex: $H_2S -- \gt HS -- \gt S^-$. - Since we've determined the stronger acids for each pair in this list, and we know that, the stronger the acid, the weaker the conjugate base, and vice versa, all we need to do is, identify the conjugate base of the weaker acid, and classify it as the stronger base of the pair.
