Question

Which one of the following is the correct statement?

पर्याय

• $$\mathrm{HCO}{\phantom{A}}_3^{-}$$ is the conjugate base of $$\mathrm{CO}{\phantom{A}}_3^{2-}$$.

• $$\mathrm{NH}{\phantom{A}}_2^{-}$$ is the conjugate acid of NH₃.

• H₂SO₄ is the conjugate acid of $$\mathrm{HSO}{\phantom{A}}_4^{-}$$

• NH₃ is the conjugate base of $$\mathrm{NH}{\phantom{A}}_2^{-}$$

Answer 1

H₂SO₄ is the conjugate acid of $$\mathrm{HSO}{\phantom{A}}_4^{-}$$

Explanation:

$$\mathrm{HSO}{\phantom{A}}_4^{-}$$ accepts a proton to form H₂SO₄. Thus, H₂SO₄ is the conjugate acid of $$\mathrm{HSO}{\phantom{A}}_4^{-}$$.

$$\underset{\mathrm{base}}{\mathrm{HSO}{\phantom{A}}_4^{-}}\stackrel{+\mathrm{H}{\phantom{A}}^{+}}{\to }\underset{\underset{\mathrm{of}\mathrm{HSO}{\phantom{A}}_4^{-}}{\mathrm{conjugate}\mathrm{acid}}}{\mathrm{H}{\phantom{A}}_2\mathrm{SO}{\phantom{A}}_4}$$
