- The concentration of CO in air is determined by passing a known volume of air through a tube that contains I2O5, forming CO2and I2. The I2 is removed from the tube by distilling it into a solution that contains an excess of KI, producing I3-. The I3-is titrated with a standard solution of Na2S2O3. In a typical analysis a 4.79-L sample of air is sampled as described here, requiring 7.17 mL of 0.00329 M Na2S2O3 to reach the end point. If the air has a density of 1.23 × 10–3 g/mL, determine the parts per million CO in the airThe level of dissolved oxygen in a water sample can be determined by the Winkler method. In a typical analysis, a 100.0-mL sample is made basic, and treated with a solution of MnSO4, resulting in the formation of MnO2. An excess of KI is added, and the solution is acidified, resulting in the formation of Mn2+ and I2. The liberated I2 is titrated with a solution of 0.00870 M Na2S2O3, requiring 8.90 mL to reach the starch indicator end point. Calculate the concentration of dissolved oxygen as parts per million of O2.The chloride ion content of a 250.0-mL seawater sample was titrated against 0.1102 M silver nitrate, requiring 13.56 mL to reach end point. How many moles of chloride ion is present in the sample?
- a. Balance the following redox in acidic media C2O42- (aq) + MnO4- (aq) → CO2(aq) + Mn2+ (aq) b. If you titrated this reaction to determine the moles of C2O42-, the colormetric endpoint is pink due to the Mn2+. How many moles of the oxalate (C2O42-) existed in solution if 12 mL of 0.791M permanganate was needed to hit the endpoint?Rei and Akari, two vinegar enthusiasts, are each tasked to determine the aceticacid content of their respective vinegar concoctions by titration. First, a 1M-labeled KOH solution was standardized against the KHP (MW = 204.22 g/mol)standard that is 99.4% pure. In the process, 0.540 g KHP was found to require2.80 mL of the KOH solution to completely react up to the phenolphthaleinendpoint. Then, Rei and Akari both prepared their samples by taking 10.0-mLaliquots of each vinegar and diluting them to 25.0 mL. Using the same titrant andindicator, Rei’s vinegar required 18.60 mL of the standardized titrant to reach theendpoint, while Akari’s vinegar required 16.50 mL of the same titrant to reach thesame endpoint. What is the exact concentration of the KOH titrant in molarity? What is the balanced chemical equation between the analyte and the titrant? What is the color transition (color X color Y) expected throughout thecourse of titration? What is the acetic acid concentration of Rei’s and…Suppose, in an experiment to determine the amount of sodium hypochlorite in bleach, you titrated a 21.63 mL21.63 mL sample of 0.0100 M KIO30.0100 M KIO3 with a solution of Na2S2O3Na2S2O3 of unknown concentration. The endpoint was observed to occur at 14.66 mL14.66 mL . How many moles of KIO3KIO3 were titrated?

- Twenty vitamin C tablets (total mass = 6.3561 g) were powdered and 0.3181 g dissolved in dilute sulphuric acid. This solution was then titrated with 0.0973 M ammonium cerium (IV) sulphate and 23.24 mL required to reach the end-point. Given that ammonium cerium(IV) sulphate reacts with ascorbic acid in a 2:1 ratio, calculate the mass of ascorbic acid (in mg) per average tablet.
