Which of the following do not represent a conjugate acid-base pair? For those pairs that are not conjugate acid-base pairs, write the correct conjugate acid-base pair for each species in the pair.
a. H2SO4, SO42-
b. H2PO4-, HPO42-
c. HClO4, Cl-
d. NH4+. NH2-
Interpretation:
The pair that do not represent a conjugate acid-base pair should be identified and the correct pair should be determine for them.
Concept Introduction:
An acid forms conjugate base by donating a proton and a base forms conjugate acid by accepting a proton. The formation of conjugate acid and base is represented as follows:
Reason for correct option:
From the loss of a proton from
