Match each substance with the correct designation for the equation HSO3- + CH3NH2 <=> SO32- + CH3NH3+ HSO3- CH3NH2 SO32- CH3NH3+ A. conjugate base of HSO3- B. conjugate acid of SO32- C. conjugate acid of CH3NH2 D. conjugate base of CH3NH3+

: conjugate acid of

: conjugate base of

: conjugate base of

: conjugate acid of

Explanation:

According to the Bronsted-Lowry conjugate acid-base theory, an acid is defined as a substance which looses donates protons and thus forming conjugate base and a base is defined as a substance which accepts protons and thus forming conjugate acid.

Here in forward reaction is accepting a proton, thus it is considered as a base and after accepting a proton, it forms which is a conjugate acid.

And  is losing a proton, thus it is considered as an acid and after loosing a proton, it forms which is a conjugate base.

Similarly in the backward reaction, is loosing a proton, thus it is considered as a acid and after loosing a proton, it forms which is a conjugate base.

And  is accepting a proton, thus it is considered as a base and after accepting a proton, it forms which is a conjugate acid.
