Vedclass · Answer

(A) The strength of a conjugate base is inversely proportional to the strength of its corresponding acid.$K_a$ values are given as: $HSO_4^- (1.2 	imes 10^{-2}) > H_2PO_4^- (6.3 	imes 10^{-8}) > HCO_3^- (4.7 	imes 10^{-11})$.Since $HCO_3^-$ is the weakest acid among the given species,its conjugate base,$CO_3^{2-}$,will be the strongest base.Therefore,the correct option is $A$.

Given the following $K_a$ values,determine which species is the strongest base: $HSO_4^- = 1.2 \times 10^{-2}$,$H_2PO_4^- = 6.3 \times 10^{-8}$,$HCO_3^- = 4.7 \times 10^{-11}$.
