Question

Which of the following is a conjugate acid-base pair?

a)NaF and F ^-

b)H3O^+ and OH^-

c)None of these

d)all of these

e) HNO3 and HNO2

Answer 1

Dr. J.R. S gave a correct answer!

What I wish to add is that in addition to the difference of a hydrogen atom, there has to be a unit of positive charge, overall a hydrogen cation.

Answer 2

I think you may have asked this question before and as I recall, the answer provided was correct. If you don't understand it, explain why and maybe we can help you out.

c) none of these is the correct answer.

The difference between conjugate acid-base pairs is the presence or absence of a hydrogen atom. An example would be NH3 and NH4+ would be conjugate pairs with NH3 being the base and NH4+ being the conjugate acid.
