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

6. A student carried out a non-aqueous titration at chemistry laboratory using 0.1N solution of HCIO4 acid. She obtained with 0.06 N as the calculated normality of HCIO4 acid after the standardization. Standardized HCIO4 acid was titrated with 0.2 g of Ephedrine hydrochloride in mercuric acetate solution. Calculate the percentage of Ephedrine hydrochloride. Volume of titrant consumed at end point was 25 mL. Note: 1 ml of 0.1 M HCIO4 acid is equivalent to 0.02017 g of Ephedrine hydrochloride.

A student does not filter his/her saturated solution before titrating. Will the calculated Ksp probably be too high, too low, or unaffected? Why? Solid substances are not part of equilibrium equations, so their presence would leave the value of Ksp unaffected. The remaining solids would absorb excess H30+ ions during the titration, making the calculated value of [OH ], and thus Ksp, too low. O The remaining solids would dissolve during the titration to give more OH¯. The calculated Ksp would therefore be too high.
