H2S can be analyzed by titration with coulometrically generated I2. The I2 is generated electrolytically from the I- in KI via:2I-(aq) ------> I2(aq) + 2e-The generated I2 then reacts in a 1:1 titration via:H2S(aq) + I2(aq) --------> S(s) + 2H+(aq) + 2I-(aq)Analysis of 50.00mL of a solution containing H2S was analyzed with dissolved KI. Electrolysis required 812 seconds at 52.6mA current. What is the [H2S] in the original solution?

The titration of 0.2121 g of pure Na2C2O4 (134.00 g/mol) required 43.31 mL of KMnO4. What is the molar concentration of the KMnO4 solution? Given that the chemical reaction is 2MnO4- + 5C2O42- + 16H+ -----> 2Mn2+ + 10CO2 + 8H2O Provide a detailed solution.
e) via:. Lisbeth Myla CHEM 3321 A Back titration - Homework A solution containing Cl- was analyzed as follows in a back titration. A solution containing (excess) Ag + is added, and the AgCl precipitate is filtered and removed. The excess Ag is then titrated with SCN- Ag+ (aq) + Cl(aq) - Ag+ (aq) + SCN (aq) -------> AgCl (s) --------> AgSCN (aq) In one analysis, 25.00 mL of 0.01840 M AgNO3 (aq) was added to 50.00 mL of a solution containing dissolved chloride. The resulting AgCl (s) was filtered and removed. The excess Ag+ (aq) remaining required 14.25 mL of 0.02008 M SCN (aq) to reach the endpoint. What is the original concentration of Cl (aq) in the original 50.00 mL soln?

A student wanted to determine the amount of NaOCI in a commercial bleaching solution. He diluted 2 g of bleach in a 100 ml volumetric flask. A 50 ml sample of the diluted bleach was mixed with excess acidified potassium iodide KI and a few drops of an indicator. The resulting solution was titrated with Na-S.O, solution. The titration required 17 mL of 0.05M Na,S,O, solution. The series of reactions that take place during this experiment: 21+OCI+ 2H1₂ + Cl + H₂O 1₂+28,0,³ →21+S,0,² a) Calculate the number of moles of OCI- in 50 mL diluted bleach and in 100 mL.
