Testing the concentration of Vitamin C in different juices and fruits

5. Prepare the salt solution by mixing 1/8 teaspoon of salt and three cups of water in a clean pitcher or 2-liter bottle. Stir or shake the solution until it is dissolved. This will produce a 1% salt solution.

Then added 5.00g of CuCl₂ ●H₂O into the distilled water. Stirred to dissolve the mixture

Place 100 ml of distilled water in a 250-ml (or 400-ml) beaker. Add 1.26g of oxalic acid dihydrate (H2C2O4.2H2O) and 1 ml of concentrated ammonia. Stir the mixture until the solid has dissolved completely.

The greater the amount of vitamin C there is in the juice, the less juice it will take to decolourise it

2) Rinse the solid with about 30 mL of distilled water and decant the liquid from the solid. It is critical that as little solid as possible is lost during this process. Repeat the rinsing two or three times.

Fill granulated cylinder with water by submerging and make sure no bubbles at the top.

First, the 1 M HCI would need to be diluted. Use 3 (.75) parts water and 1 part (.25) 1 M HCI.

(Sinno et al, 2011). It also helps in the transfer of white blood cells to the wound, improves resistance to infection and increases capillary strength. Since vitamin C is water-soluble, it is difficult to store it in the body, so a regular intake is necessary and dietary sources are green vegetables, potatoes, fruits like orange, kiwi and berries. (Timms, 2011).

Stir gently and add one drop of hand washing soap. (Avoid bubbles) 6. Obtain a new cup and add 50mL of 70% isopropanol and 3 drops of dye 7. Gently pour the solution slowly into the salt water solution to form a thin layer. 8.

Boil up the mixture on medium warmth until the water is decreased by a third and after that let it cool for some time.

Vitamin C helps to produce collagen. It is also vital in the production of dopamine and adrenaline, and necessary to the function of almost all major organs. Low levels of ascorbic acid can result in loose teeth, anemia, inability to heal quickly, and easier bruising. In general, though, people with fairly healthy diets get enough of this

Vitamin C also known as ascorbic acid is needed for growth and maintenance of healthy tissues, especially skin, blood vessels, bones, gums, teeth. Vitamin C aids in resistance against infection and healing of wounds. It also helps the body absorb iron from food. Vitamin C can be found in green vegetables, potatoes, tomatoes and citrus fruits such as oranges and lemon. A lack of vitamin C can cause scurvy, iron deficiency and poor wound healing. A healthy diet

After I collected the data the how much Iodine reacted, I averaged my measurements and used those value in calculations. This approach helped me to minimize the different errors of measurement. The concentrations of Ascorbic Acid could be calculated by referring to the values of Iodine solution as a standard. Finally, I found that Cran-apple juice has the highest concentration of Vitamin C, Green Tea has the second highest, then Rose Hips, and orange has the least concentration of Vitamin C. These results are shown in the graphs. However, the results did not support my

2. Add about 20 mL of distilled water and stir the mixture with a glass stirring rod to dissolve the sample. There may be a small amount of insoluble residue. If your sample does not dissolve completely, remove the insoluble material by filtration.

Vitamin C is crucial for survival for several reasons. For a human body to reach the acme of its physical potential, it must have a daily intake of vitamin C. Deficiency can lead to a fatal symptom known as scurvy. Likewise, iron absorption will be more difficult resulting in iron-deficiency anemia (Smith, Primio & Humphrey-Murto, 2011). However, this nutrient is essential for bodily functions as well. Vitamin C is required for hormone production which is seen by the fact that the highest concentration of it in the human body is in the pituitary and adrenal glands (Emsley, 2004). Moreover, this vitamin aids in protection against free radicals and stress. Vitamin C is also imperative because it assists in the growth of various body parts, including teeth, cartilage, and dentine. This acid is integral for bone development and to heal fractured or broken bones. As said before, “Vitamin C is important in the absorption and metabolism of many nutrients that affect production of red blood cells”, including iron absorption (Smith, Primio, & Humphrey-Murto, 2011).
