THE VITAMIN C CONTENT OF FRUIT JUICE Aim: To investigate the vitamin C content of fruit juice.Hypothesis: I believe the more drops of fruit juice taken to decolourise DCPIP‚ the smaller the amount of vitamin C in that fruit juice. This is because DCPIP needed to be decolourised by ascorbic acid in fruit juice‚ so less concentration of ascorbic acids means that more ascorbic acids is needed to decolourised DCPIP. I believe that freshly squeezed orange is going to have the most Vitamin C content

GCSE SCIENCE COURSEWORK (CHEMISTRY) PLANNING: Skill Area P Write down the aim of your Investigation. To investigate the effects of change in concentration on the rate of reaction between Sodium Thiosulphate and Hydrochloric Acid. Briefly describe your Preliminary Experiment and include your results. Explain how these results have helped you plan your main experiment (p8b). An increase in concentration will lead to an increase in the rate of reaction because there will be a greater number of

Title : The Vitamin C content of fruit juice Aim : To investigate the vitamin C content of fruit juice. Introduction : [2]Vitamin C‚ also known as the ascorbic acid or the L-ascorbate‚ is required for the growth and repair of tissues in all parts of our body. It is necessary to form collagen‚ an important protein used to make skin‚ scar tissue‚ tendons‚ ligaments‚ and blood vessels. Vitamin C is essential for the healing of wounds as well as for the repair and maintenance of cartilage‚ bones
