1. An acidic solution is known to contain 1.1402 g of a dissolved, chloride containing sample. A 0.6447-g portion of manganese dioxide (MM: 86.94 g/mol) was added to this same solution, and the following reaction occurs: MnO2 (s) + 2 CI` + 4 H* ® Mn*2 + Cl2 (2) + 2 H20 After the reaction is complete, the excess MnO2 is collected by filtration, washed, allowed to dry, and is then weighed; 0.3521 g are recovered. Find the percent mass of chloride in the original sample. Do not consider any equilibria - assume the reaction proceeds completely to the right.

Tungsten trioxide (WO,) has a rich yellow color and is often used as a pigment in ceramics and paints. To test a ceramic vase for its WO, content, a 10.15 g sample of the vase was ground and reduced with Pb(Hg) to convert any WO, to W³+. The resulting W3+ was transferred to 500.0 mL of 1.00 M HCI. A 100.00 mL aliquot of the HCl solution required 14.78 mL of 0.08271 M potassium permanganate (KMNO,) to reach the purple endpoint. A blank required 0.26 mL.

A sample of iron ore is dissolved in acid, and the iron is converted to Fe2+ (iron II). The sample is then titrated with 57.30 mL of 0.03240 M MnO4- solution. The net ionic equation for the oxidation-reduction that occurs during titration is as follows: Mn04-(aq) + 5FE2+(aq) + 8H+(aq) --> Mn2+(aq) + 5FE3+(aq) + 4H2O(I) How many moles of Fe2+ were in the sample? O 2.269 x 10^-2 mol (2.269E-2 mol) O 7.563 x 10^-3 mol (7.563E-3 mol) O 9295.1 mol O 5 mol O 9.285 x 10^-3 mol (9.285E-3 mol)
The blood alcohol C2 H; OH level can be determined by titrating a sample of blood plasma with an acidic potassium dichromate solution, resulting in the production of Cr*+ (aq) and carbon dioxide. The reaction can be monitored because the dichromate ion (Cr2 O,²) is orange in solution, and the Cr³* ion is green. The unbalanced redox equation is Cr2 O,2 (aq) + C2H; OH(ag) → Cr³* (ag) + CO2 (g) If 40.35 mL of 0.0711 M potassium dichromate solution is required to titrate 27.5 g of blood plasma, determine the mass percent of alcohol in the blood.
