Step 1: Answer:
H3O+ is the conjugate acid in the following reaction
Step 2:: Explanation
. When a base dissolves in water, the species that gains a hydrogen (proton) is the base's conjugate acid
Simply we know that
A conjugate acid contains one more H atom and one more + charge than the base that formed it.
A conjugate base contains one less H atom and one more - charge than the acid that formed it.
When the HC2H3O2(aq) reacts with H2O, the H3O+ cation is the conjugate acid that forms since it gains a H atom and more + charge
