Investigating Vitamin C Background Vitamin C is found in green vegetables‚ fruits‚ and potatoes. It is essential for a healthy diet. The chemical name for vitamin C is ascorbic acid. Ascorbic acid is a good reducing agent and therefore it is easily oxidised. Methods for the detection of vitamin C involve titrating it against a solution of an oxidising agent. Where to start There are several oxidising agents that can be used and a commonly used one is 2‚6-dichlorophenol-indophenol or DCPIP

Among the different viruses‚ hepatitis C is the most serious because it can be chronic and cause severe liver damage. During the initial infection people often have mild or no symptoms. Occasionally a fever‚ dark urine‚ abdominal pain‚ and yellow tinged skin is there. Early on chronic infection typically has

IB Biology Lab – Vitamin C content of food Aim: To compare the vitamin C content of different fruits using the decolourisation of DCPIP from blue to clear as the indicator. • You first need to estimate the volume of a known concentration of vitamin C solution required to decolourise 2 cm3 of DCPIP solution. • Then you need to determine the volume of fruit juice that decolourises 2 cm3 of DCPIP solution. This gives an estimate of the concentration of vitamin C in fruit juice. • This

Investigating the vitamin C content of fruits and fruit juice Aim: In this investigation‚ I aim to measure and compare whether there is a higher content of vitamin C in a fruit or a juice by measuring the volume of the sample required to decolourise a solution of dichlorophenolindophenol (DCPIP). Introduction: For this experiment‚ I aim to investigate and compare the content of vitamin C in the fruit against the fruit juice. The theory of this method is a titration with dichlorophenolindophenol

Lab Report: MEASUREMENT OF VITAMIN C Introduction Nutritional diseases were once the number one cause of death only a century ago‚ but rarely affect our lives today. The complete lack of vitamin C (ascorbic acid) characterized by dark purple spots on the skin and rotting gums‚ a disease called scurvy‚ took the lives of many sailors up until the mid 1800s when the prevention was discovered. Consequently‚ British sailors became referred to as ‘limeys’ because of their daily habit of eating

The C-130 The C-130 Hercules was born from a request by the United States Air Force for a replacement transport aircraft for the C-119 Flying Boxcar‚ C-47 Skytrain‚ and C-46 Commando‚ which were inadequate for modern warfare after the Korean War. The USAF wanted a plane that could have a capacity of 92 passengers‚ 72 combat troops or 64 paratroopers fly a range of around 1‚100 nautical miles‚ have the ability to fly with one engine shut down‚ and be able to take-off from unprepared runways (MotoArt

Vitamin C Molecule Investigation Thomas Philpott Introduction Vitamin C (ascorbic acid) is an essential component of human nutrition‚ as it is an antioxidant that the body requires. Having a deficiency in Vitamin C can lead to scurvy‚ a disease characterized by abnormalities in human bones and teeth. Fruits and vegetables are common sources of Vitamin C‚ notably oranges and citrus fruits. Cooking and the application of heat destroy the vitamin so such fruits must be raw in order to obtain the

Abstract Vitamin C‚ also known as ascorbic acid‚ is a water soluble vitamin that is regarded as one of the safest and most effective nutrients. Vitamin C can be found in most fruits and vegetables. The goal of the experiment is to find out the concentration of vitamin C in three citrus fruits‚ orange‚ lemon and lime‚ and to compare them and find out which fruit contains the highest concentration of Vitamin C. By using the juice from each fruit to make a solution to combine with 10cm³ of DCPIP until
