It can be used to test for vitamin C
Vitamin C is an organic chemical. it can be offered in solution (as with orange juice) or as a dry powder.
Standardise it with iodine, dcpip or use its reaction with iron
The concentration of vitamin C in the solution decreases.
Iodine makes a good indicator. The iodine will blend into the surrounding color. Once their is no more vitamin c then the iodine will start to chemically combine with any starches
Pink
it means that your body does not have enough vitamin c, i would recommend if your vitamin c levels are low to go to the store and buy some vitamin c tablets. cause your body needs vitamin c.
we can measure the amount of vitamin C in juice through of samples and then we need to make tests analyzing the ozidizing agents... caca batty my answer will be..... 1. Mix 1 tablespoon of cornstarch into enough water to make paste. 2. To this paste, add 250ml of water and boil for 5 minutes. 3. Add 10 drops of the starch solution to 75 ml of water (use an eyedropper). 4. Add enough iodine to produce a dark purple-blue color. Now your indicator solution is ready. 5. Put 5ml of indicator solution (about 1 tablespoon) in a 15ml test tube. To the test tube, use a clean eyedropper to add 10 drops of juice. Re-clean the eyedropper for each sample. 6. Hold the test tube against a white background. Line up the tubes from lightest to darkest purple. The lighter the solution, the higher the vitamin C content. That's because vitamin C causes the purple indicator solution to lose its color. this is the solution about how you measure the amount of vitamin C..... actually.....i think mine is better than the one at the top tee hee
You can buy vitamin C at many drugstores like Walgreens and CVS. Even department stores like Wal Mart, Target, and K Mart have vitamin C for very reasonable prices.
How to test for vitamin C: 1. Draw up 2cm3 of lemon/orange juice (or the substance you're wanting to test for vitamin C) into a syringe. 2. Add it drop by drop into 2cm3 of a 0.1% solution of DCIP (a blue dye) 3. The dye will turn colourless if vitamin C is present
The Vitamin C will probably get decreased due to the food it is processed by. An example of that is if you buy a serving of Large Fries from McDonalds and the Vitamin C is processed to a Small serving of Fries then the Vitamin C will decrease because the Vitamin C in the Large Fries were larger and when it processed into the Small Fries then it got decreased because the Small Fries had a lower percent of Vitamin C than the Large Fries did.
