Why cannot one determine the relative acid strengths of HClO4 and HNO3 using aqueous solutions of these acids?
(A) The acids are insufficiently soluble for the measurements.
(B) A more basic solvent than H2O must be used.
(C) H2O is too basic a solvent for the distinction to be made.
(D) These oxidizing acids cause redox reactions to occur.
(E) Actually, the acid strengths can be determined using aqueous solutions
