TestVitamin c as Rai The purpose for1. to determine the quantity of vitamin c by means of a rolling thaitharet ok that is related to the extraction of iodine in the water.For example, plants.2. to compare the vitamin c consumption by means of thaitharet the Board related to the iodine in ok.Extraction of water from plant samples* The assumption of education.The kaphuet don't need to distill water cave ngotdotop by thaitharet the Board ok related to iodine.Change to blue. The plant's leaves don't show that sites 17 pound Mika villas.* The scope of the study.1. use the leaves of the plant, including the leaves don't d Neem, mango, the cassia and the Peacock tail.2. the titration the iron ok iodine is related are nawitamin in water quantity raham come to extract the plants don't d A.Device and method for trial.1. cooked flour, water.2. the water extracted from the cache.3. water extracted from Moringa leaf4. the extraction of water from mayom5. water extraction from the matum guest.7. experimental medium tube8. the eyedropper9. the injection tubeSize: 50 ml beaker, 10.11. Fruit Smoothie12. experimental tube area 12 cm.13. spring scales14. iodine solution15. vitamin c solutionExperimental methods.1. prepare the extraction plant by a plant, each of them spinning, and then split the split came to each beaker.2. put the water, flour, cooked down in four medium-sized tubes. 2 cm.Then the drip tube, 1 drop of iodine solution and iodine solution droplets drip tube, 1 observed changes and save the results.3. drops of solution of synthetic vitamins in 0.001%, down 1 by 1, add the drops and drips shake every time the drops until the solution gradually fade to blue. Count the number of drops that cause the blue fades. Save the results.4. perform the experiment, as well as article 2 of the second experiment by changing the bulbs from 0.001% aqueous solution of synthetic vitamin c is water extracted from the cache. Water extracted from Moringa leaf Water extracted from phyllanthus acidus Water extracted from the matum Water extracted from the cashew nut, respectively.5. try ซ้ไข้ sur 1-4 again twice record results and averages.Summary trial. From a comparison of the number of drops of water is extracted from a plant with six types of vitamin c synthesis in this experiment it was found that water extracted from Moringa leaf. The water reflecting bites from the cashew has vitamin c in the same plants and the most. Water extracted from the cache and the phyllanthus acidus are vitamin c. But with less than the Moringa leaf and cashew nut and there is more than a water extraction and the matum mayom. Experimental tube
