One of the CHEM3341 student Ms. Fatima Al Wahaibi wanted to analyse phosphate ion concentration in Fertilizer industry wastewater sample collected from Rusayl Industrial Estate using spectrophotometer method. She mixed 200.00 mL of wastewater sample which contains only Na,PO, (unknown molarity) with 400.00 mL of 0.0200 M K,PO4 in a one liter beaker to make a Solution A. She then transferred 25.00 mL of Solution A to a 250.00 mL volumetric flask and added distilled water up to the calibration mark to make up Solution B. The Concentration of phosphate ions in Solution B is known to contain 3.00 x 103 mol/L from the spectrophotometric analysis at 460 nm using 1 cm cuvette. Calculate the concentration of phosphate ion in wastewater and how many phosphate ions are present in this wastewater.

A student determined the concertration of NaOCI in a commercial bleach sample using the same technique described in section "F" of the Halogens and Their Compounds lab. The student required 18 drops of 0.01M Na25203 to reach the end point. What is the concentration (reported in percentage) of NaOCI in the bleach sample?
Note: This is an algorithm question so each attempt will have unique set of measurements. The following results were obtained when a sample of white cranberry juice was analyzed to determine its Vitamin C content. A 82.0 mL sample of the juice was placed in a flask with excess H2SO4, excess KI, and 11.00 mL of 0.07 000 M KIO3. Titration with thiosulfate solution required the use of 1.63 mL of 0.08826 M. Calculate the concentration of Vitamin C in the juice sample as mg Vit C per 100 mL juice. Here are some steps to help you work your way along the problem. All the reactions in the Background apply. • How many total millimoles of I are produced from the Reaction 4 between KI and KIO3? • How many millimoles of I are consumed in Reaction 3 with thiosulfate? . Using your previous two answers, how many millimoles of I reacted with the Vitamin C in the juice? • How many milligrams of Vitamin C were in the juice sample? • What is the concentration of Vitamin C in the juice sample expressed as…
