A 1.380 g sample containing iodoform CHI3 is decomposed in an acidic medium by 33.60 mL of 0.0845 M AgNO3 according to :
CHI3 + 3 Ag+ + 4H2O 3 AgI(s) + 3 H3O+ + CO(g)
Once the reaction is completed, the excess of silver ions argent is titrated with 3.58 mL of 0.0950 M KSCN to the E.P. Calculate
the percentage of iodoform in the initial sample.

    12.0 mL of a 437.1 mM AgNO3 solution is added to a 20.0 mL sample containing an unknown chloride ion concentration to precipitate Cl- as AgCl. The AgCl solid is removed and excess Ag+ is titrated with a standard 137.0 mM KSCN solution in the presence of Fe3+. After 2.5 mL of the standard solution have been added, all Ag+ has precipitated as AgSCN and the red complex FeSCN2+ forms. What is the chloride ion concentration in the sample to...

    A 0.7498-g sample of a chlorocarbon compound was analyzed by burning it in oxygen and collecting the evolved gases in a solution of NaOH. After neutralizing, the sample was treated with 48.85 mL of a 0.2298 M AgNO3 solution. This precipitated the chloride (Cl-) out as AgCl and left an excess of AgNO3. The excess AgNO3 was titrated with 0.1165 M KSCN and required 20.82 mL to reach the endpoint in a Volhard titration. Calculate the % w/w Cl– (35.45...
