The correct answer is C. Moles acid =(50.0 mL)(0.20 mol acid/1,000 mL)=0.0100 mol Moles base =(50.0 mL)(0.20 mol base/1,000 mL)=0.0100 mol There is sufficient base to react completely with only one of the ionizable hydrogen ions from the acid. This leaves H2AsO−4. Answer D cannot be correct because it is a cation.
