Volumetric Analysis of Vitamin C by Titration The objective of this experiment is to use a redox reaction titration to accurately determine the amount of vitamin C in a sample of lemon juice‚ orange juice‚ or grapefruit juice. Chemistry of Vitamin C The chemical name for vitamin C is L-ascorbic acid. Its molecular formula is C6H8O6; its molar mass is 176.12 g/mole. Ascorbic acid is found throughout the plant and animal kingdoms‚ occurring in citrus fruits‚ hip berries (such as rose

Aim This experiment is to determine the vitamin C content in different brands of processed fruit juices. Hence‚ compare the vitamin C content in the experimental results with the manufacturer’s claim and to find out the best buy. Principle Vitamin C (ascorbic acid) is a reducing agent‚ the vitamin C content of processed fruit juices can be determined by oxidizing ascorbic acid‚ C6H8O6 to dehydro-L-ascorbic acid‚ C6H6O6. A reagent that is particularly good for the oxidation is an aqueous solution

Investigating the Effect of Caffeine on the Heart Rate of Daphnia Daphnia are extremely small aquatic invertebrates. They are transparent‚ so you are able to see their internal organs; this means it is easy to monitor their heart rate by observing them through a microscope [1]. Physiological results from caffeine consumption include the stimulation of heart rate‚ blood pressure‚ metabolism‚ body temperature and alertness. [2] In this practical investigation the aim was to determine whether the hypothesis

question‚ or topic‚ was “Does the level of vitamin C change over time in Orange Juice.” After I viewed the website‚ I got very excited because it had simple step-by-step instructions about how to test the level of vitamin C. On the following page are the directions. I think I am really excited to do this project because it sounds very interesting and fun to do. I hope to prove what the driving question/topic entails.

Vitamins‚ Nutrients‚ and Minerals Vitamins‚ nutrients‚ and minerals are all important substances that are required to lead a happy‚ healthy life. Firstly‚ vitamins are an organic compound required by the body in small amounts of metabolism‚ to protect health‚ and for proper growth of children. Vitamins also assist in the formation of hormones‚ blood cells‚ nervous systems chemicals‚ and genetic material. There are 13 well-identified vitamins. Some examples of the 13 well-identified

classes of vitamins are Fat – soluble vitamins and water – soluble vitamins. Fat – soluble vitamins include vitamin A‚ vitamin D‚ vitamin E‚ and vitamin K. These vitamins are considered fat soluble vitamins because they are stored in the body for long periods of time and are harder to break down‚ while water soluble vitamins are not. Water – soluble vitamins include vitamin B1 (thiamin)‚ vitamin B2 (riboflavin)‚ vitamin B6‚ vitamin B12‚ and vitamin C‚ folic acid‚ and niacin. These vitamins are classified

VITAMINS AND MINERALS Vitamins and minerals make people’s bodies work properly. Although you get vitamins and minerals from the foods you eat every day‚ some foods have more vitamins and minerals than others. Vitamins fall into two categories: fat soluble and water soluble. The fat-soluble vitamins — A‚ D‚ E‚ and K — dissolve in fat and can be stored in your body. The water-soluble vitamins — C and the B-complex vitamins (such as vitamins B6‚ B12‚ niacin‚ riboflavin‚ and folate) — need to dissolve
