Equilibrium Question 798

Question: Which one of the following is the correct statemen'

Options:

A) $ HCO_3^{-} $ is the conjugate base of $ CO_3^{2-} $ .

B) $ NH_2^{-} $ is the conjugate acid of $ NH_3 $ .

C) $ H_2SO_4 $ is the conjugate acid of $ HSO_4^{-} $ .

D) $ NH_3 $ is the conjugate base of $ NH_2^{-} $ .

Show Answer

Answer:

Correct Answer: C

Solution:

$ HSO_4^{-} $ accepts a proton to form $ H_2SO_4 $ Thus $ H_2SO_4 $ is the conjugate acid of $ HSO_4^{-} $

$ \underset{base}{\mathop{HSO_4^{-}}},\xrightarrow{^{+{H^{+}}}}\underset{conjugate,acid,of,HSO_4^{-}}{\mathop{H_2SO_4}}, $
