Question

write down the conjugate bases of following Bronsted acids : HCl, H²S, H²SO4 , HNO³​

Answer 1

Answer:

Conjugate base of HCL - Cl-

Conjugate base of H²S - HS-

Conjugate base of H²SO4 - HSO4-

Conjugate base of HNO³​ - NO³​-

Answer 2

The conjugate bases are as follows-

$Cl^-\\S^{2-}\\SO_4^{2-}\\NO_3^-$.

• When bronsted acids release a hydrogen ion and converted it to an anion that anion is called a conjugate base.
• Thus HCl dissociate as-
• $HCl\rightarrow H^++Cl^-$ and produce $Cl^-$ as a conjugate base.
• Thus $H_2S$ dissociate as-
• $H_2S\rightarrow 2H^++S^{2-}$ and produce $S^{2-}$ as a conjugate base.
• Thus $H_2SO_4$ dissociate as-
• $H_2SO_4\rightarrow 2H^++SO_4^{2-}$ and produce $SO_4^{2-}$ as a conjugate base.
• Thus $HNO_3$ dissociate as-
• $H_2S\rightarrow H^++NO 3^{-}$ and produce $NO_3^-$ as a conjugate base.
