Modified Arrhenius theory question?

using the modified Arrhenius theory, write a chemical reaction equation to explain the acidity of glycolic acid.

1 answer

Arrhenius' theory. An acid is a substance that produces H^+ in solution.
HCl(aq) ==> H^+ + Cl^-
or if you want to use H3O^+, then the reaction
HCl + H2O ==> H3O^+ + Cl^-
Since HCl produces H^+ in solution (or more accurately H3O^+ in solution), HCl is an acid.
I saw this same question on Yahoo. I wonder if you posted it.
