In the Vitamin C analysis, you determined Vitamin C content in a tablet using redox titration method. Calculate the mass of vitamin C in the tablet which was dissolved in 50 mL of water. A 25 mL aliquot of this stock solution was titrated with 18.5 mL of a 0.0250 M KIO3 to the blue starch end point. If the same KIO3 solution was used to titrate 20 mL of a commercial juice blend and the juice blend required 1.5 mL of KIO3 to reach the end point. How many milligrams of vitamin C are in the sample of juice blend? Molar mass Vitamin C= 176.16 g/ml.

Five white, 500-mg uncoated ascorbic acid (AA) tablets with an average weight of 0.6152-g were pulverized in a mortar. A sample of the powdered ascorbic acid weighing 0.4700-g was placed in an iodine flask and was dissolved in 50-mL H2SO4 then 5-g of KBr was added to the resulting solution. The solution was titrated with 47.81-mL of 0.09640 N STD. KBrO3 to reach a faint yellow endpoint then 3-g KI and 5-mL Starch TS. The blue color solution is then titrated with 2.73-mL of 0.09123 N STD. Na2S2O3 to reach the disappearance of the blue iodostarch complex.

The ethyl acetate concentration in a alcoholic solution was determined by diluting a 10.00 mL sample to 100.00 mL. A 20.00 mL portion of diluted solution was refluxed with 40.00 mL of 0.04672 M KOH. Ater cooling, the excess OH2 was back-titrated with 3.41 mL of 0.05042 M H2SO4. Calculate the amount of ethyl acetate (88.11 g mol) in the original sample in grams.
An analyte solution was prepared using 1.1278 g of a diprotic acid and 25.0 mL of distilled water. A 5.0 mL aliquot was then taken and diluted to 50.0mL. During titration, it required 19.4 mL of a 0.0356 M standardized NaOH solution to reach the end point. a.) What is the molarity of the undiluted analyte solution? b.) What is the molecular weight of the diprotic acid?
The concentration of Cl– in a 300.0-mL sample of water drawn from a fresh water acquifer suffering from encroachment of sea water, was determined by titrating with 0.0516 M Hg(NO3)2.

The total cation content of natural water is often determined by exchanging the cations for hydrogen ions on a strong acid ion-exchange resin. A 25.00 mL sample of a natural water was diluted to 100.00 ML with distilled water, and 2.06 g of a cation - exchange resin was added. After stirring, the mixture was filtered and the solid remaining on the filter paper was washed with three 15.00 mL portions of water. The filtrate and washings required 16.30 mL of 0.0282 M NaOH to give a bromocresol green end point. a) Calculate the number of millimoles of cation present in exactly 1.00 L of sample. b ) Report the results in terms of milligrams of CaCO3 per liter.
