IDENTIFY THE CONJUGATE ACID-BASE PAIR IN THE FOLLOWING REACTIONS.
A) HSO4^- + SO3^2- <---> HSO3^- + SO4^2-
B) S^2- + H20 <----> HS^- + OH^-
C) CN^- + H3O^+ <----> HCN + H2O
D) H2SE + H2O <----> HSE^- + H3O^+
What do you not understand about this? Look for the ion that has an H on one side and one fewer H on the other side. That's all there is to it.
so which one is the acid and which one is the base
The one with more H is the acid and the one with one fewer H is the base.
HSO4^- is the acid. SO4^2- is the base.
SO3^2- is the base; HSO3^- is the acid.
