6. A student who wants to make chloride determination by Volbard method; a) To adjust the KSCN solution to be used as a titrant, she takes 5 mL of 0.0987 M AGNO3 solution into a flask and titrates it with KSCN solution in the presence of iron (III) ammonium sulfate indicator. If 4.8 mL of titrant was consumed as a result of titration, find concentration of KSCN solution in molarity? b) For the determination of Ct in a sample, 10.0 mL of 0.0987 M AGNO3 is added to the sample given in a flask and titrated with the adjusted (in part a) KSCN solution in the presence of iron (II) ammonium sulfate indicator. Since 2.8 mL of titrant is consumed as a result of titration, how many mg of chloride does the sample contain? (Cl: 35.5 g/ mol) 1ox0.098 2
