When a solution of an oxidizing agent is titrated with a solution of a reducing agent and the initial concentrations of the two solutions Tre the same, does that mean that the equivalence point will be reached when an equal volume of reducing agent solution has been added? Select one: O a. Yes, equivalence point will be reached O b. Not enough information to make a decision O C. No, equivalence point will not be reached O d. Oxidizing and reducing agent solution cannot be used in titration,
