Vedclass · Answer

(B) The strength of a conjugate base is inversely proportional to the strength of its corresponding acid. Stronger acids have weaker conjugate bases,and weaker acids have stronger conjugate bases. The corresponding acids for the given conjugate bases are: $ClO_4^-$ comes from $HClO_4$ (a very strong acid). $HCO_3^-$ comes from $H_2CO_3$ (a weak acid). $F^-$ comes from $HF$ (a weak acid). $HSO_4^-$ comes from $H_2SO_4$ (a strong acid). Comparing the acid strengths: $HClO_4 > H_2SO_4 > HF > H_2CO_3$. Therefore,the order of conjugate base strength is $HCO_3^- > F^- > HSO_4^- > ClO_4^-$. Thus,$HCO_3^-$ is the strongest conjugate base among the given options.
