Fill Beaker #1 with 16 ounces of water.
Crush the 500 mg vitamin C tablet and pour the pieces into the water. Thoroughly stir to completely allow the vitamin C to dissolve.
From this solution, measure out an ounce and transfer it to Beaker #2. Dispose of the remaining contents of Beaker #1.
Add 4 ounces of water to Beaker #2 and mix thoroughly (the beaker will now contain roughly 31 mg of vitamin C).
In Beaker #3, add 1 teaspoon of cornstarch to 2 tablespoons of water. Thoroughly stir until a consistent texture is reached.
Separately, boil 4 ounces of water and pour into Beaker #4.
Add the contents of Beaker #3 to Beaker #4 and thoroughly stir.
Set aside Beaker #4 to cool.
Once Beaker #4 has reached room temperature, add and thoroughly stir

After each drop, stir the solution for 15 seconds.
Record the number of drops it takes to reach a solid blue color (can be written off to the side).
Calculate the amount of iodine droplets required to oxidize 1 mg of vitamin C
In order to do so, divide the number of drops it took to fulfill the blue color by 31, which was the the amount in milligrams of Vitamin C in Beaker #2. For example, if it took 93 drops to reach the blue color, the equation would be (93 / 31 = 3). In terms of this example, it takes 3 drops of iodine to oxidize 1 mg of vitamin C.
Record the number of drops required to oxidize 1 mg of vitamin C.
Procedure 2 (Apple Juice):
Record the amount of apple juice being used (50 mL).
Pour the juice into a beaker and prepare the water bath to 50°C
Place the beaker in the water bath and start the stopwatch
After 180 seconds, remove beaker from the waterbath
In Beaker #5, add 1 ounce of the fruit juice to 4 ounces of water. Thoroughly stir.
Add 1 teaspoon of the contents of Beaker #4 (same solution used in previous procedure) to the Beaker #5 and stir well.
Use the pipette to add iodine, drop by drop, into Beaker #5.
After each drop, stir the solution for 15
Start with the hot water and first measure the temperature. Record it. 8. Then pour 40 ml into the beaker. You can measure how much water was used by looking at the meniscus.
We then took 1ml of the 0.1% solution from test tube 2 using the glucose pipette and added it to test tube 3, we then used the H2O pipette and added 9ml of H2O into test tube 3 creating 10ml of 0.01% solution.
Each subsequent trial will use one gram more. 2.Put baking soda into reaction vessel. 3.Measure 40 mL vinegar. 4.Completely fill 1000 mL graduated cylinder with water.
3.) Divide your 30g of white substance into the 4 test tubes evenly. You should put 7.5g into each test tube along with the water.
2. Drop a gummy bear into each of your prepared beaker or cup and place the beaker or cup
This experiment will determine the levels of Vitamin C present in each of the different fruit juices selected. The level of Vitamin C will be compared between each fruit juice to determine which one has the highest amount of Vitamin C. Several drops from one fruit juice will be mixed into an iodine solution then repeated with a different fruit juice. With every drop of fruit juice a chemical reaction occurs and the process continues until the solution becomes colorless. The reaction will vary in according to the amount of Vitamin C present in each one of the different fruit juices.
Third, grab the left edge of the Kool-Aid packet between your thumb and index finger. With your other hand, begin peeling the upper-left corner until the entire top of the envelope is removed. Next, dump the contents of the envelope into the pitcher. Notice how the powder floats before settling on the bottom of the pitcher. Then, take the measuring cup and scoop two cups of sugar into the pitcher as well. At this point, adding the water is a crucial step. Place the pitcher under the water faucet and slowly turn on the cold water. If the water is turned on too quickly, powder will fly all over when the initial gusts of water hit. After the pitcher is filled within two inches of the top, turn the water off and get prepared to stir. With the wooden spoon submersed three-quarters of the way in the liquid, vigorously stir in a clockwise motion until all of the powder is dissolved.
7. Using the stirring wire, stir the mixture until the solute completely dissolves. Turn the heat source off, and allow the solution to cool.
According to Witney and Rolfes 2012, Vitamin C is a water-soluble vitamin that is necessary for normal growth and development. Water-soluble vitamins dissolve in water and leftover amounts of the vitamin leave the body through the urine. Hence the reasons why we need a continuous supply of this vitamin our diet. Vitamin C in humans must be ingested for survival. It is an electron donor, and this property accounts for all its known functions. As an electron donor, vitamin C is a potent water-soluble antioxidant in humans.
Remove the metal object from the first beaker and insert it into the second one.
Remove the extra solvent on a steam bath under a hood while flushing the flask with N2 gas, leaving the crude extract. Weigh extract.
Vitamin C is an essential in the body's defenses against infection. Susceptible children will not tolerate relatively unimportant infections and this can lead to prolonged illness and in the case of behaviorally disturbed children of symptoms previously well managed. Vitamin C is an extremely safe substance which is immensely beneficial to the brain and body in a multitude of ways. Its potential for preventing and treating autism has barely been touched. Vitamin C is heavily concentrated in the brain, but its exact role in brain function has not been fully understood. A recent search turned up 400 references referring to vitamin C and the effects of the brain, but the mystery still remains.
Plan 1. Collect 4 different sized beakers 2. Boil some water in the kettle 3. Pour 50ml into each beaker 4. After 1 minute check temperature 5.
2. In the large beaker, put water and boil it completely. After that, remove the beaker from heat. 3. Sample tubes (A-D) should be labeled and capped tightly.
Vitamin C is one of the most important vitamins. Without vitamin C, human life would not be on this planet today. It does many positive things in the human body. It increases recovery time from illnesses such as colds. It helps to prevent free radical damage and collagen glycation, which cause the body to age much faster than it usually should. It also helps to prevent major diseases, like scurvy, which results from Vitamin C deficiency. Vitamin C is necessary for human life.
