During Lab 4, you are titrating a sample of new orange juice to determine its ascorbic acid (aka vitamin C) content. You have previously determined an experimental conversion factor of 0.26 mg ascorbic acid/mL dye using an ascorbic acid standard. After measuring out 5.16 mL of your orange juice sample and ~10 mL of 3% metaphosphoric acid to a graduated cylinder, you dilute the solution to 50.33 mL with DI water. You finally dispense 10.87 mL of the diluted solution into an Erlenmeyer flask, add 4 drops of HCl, and use 6.48 mL of dye to reach the equilibration point. How much ascorbic acid (mg) is in your concentrated orange juice sample? The molecular weight of ascorbic acid is 176.12 g/mol.
Find out the vitamin C content. Put vitamin C in sulfuric acid and then rinse with water, 250cm3. Pull out 25cm3 and put it into the Erlenmeyer flask, then put Ki and finally KIO3. I want to ask why we need to put vitamin c, KI and KIO3 in order? Then drip this solution with Na2s2O3
If you purchase 1 bottle of 120 tablets of 650. mg sodium bicarbonate in the pharmacy aisle (the cheapest I found was $4.99), you are paying a significant amount of money for the bottling, capsuling and mark-up. You can purchase for $28.99 at www.amazon.com 30.0 pounds of sodium bicarbonate. How many bottles of tablets can you make out of the 30.0 lbs of NaHCO3 if you already have the capsules, labeling and bottles? If you are able to sell each bottle for $4.99 , once subtracting the $28.99 for the cost of the sodium bicarb, what is the gross profit before other bills?
