Identify the conjugate base of the following acids? The names. For example HCl is hydrochloric acid.

A) HSO4^-
B)H3O^+

This is the opposite of your other post.Here the problem gives you the acid and you are asked to give the base. So take a H^+ away.

HSO4^- minus a H^+ = SO4^2-
H2O^+ minus a H^+ = H2O
