Question- A 100.0 mL solution containing aqueous HCl and HBr was titrated with 0.1220 M NaOH. The volume of base required to neutralize the acid was 45.36mL. Aqueous AgNO3 was then added to precipitate the Cl- and Br- ions as AgCl and AgBr. The mass of the silver halides obtained was 0.9873g. What is the molarity of the HBr in the original solution?
