Project Title: Examination of bacterial content of sea water samples from selected sites in South East England Introduction Over the past few years coastal beaches across the UK has seen lavished with recognition for their cleanliness‚ by sections of the media and various organisarions. Majority of these beaches have been awarded the Blue flag award in recognition for meeting set criteria on various standard including cleanliness‚ water quality‚ environmental management and environmental education

What would the world be like if one day technology was inaccessible? Technology is used extensively in the healthcare department to provide patients with the best treatment. This is especially the case at the Mount St. John’s Medical Centre (MSJMC)‚ where technology must be up to date‚ easy to use‚ and designed to aid doctors to make the best and fastest decision with accurate information. Technology is best described as “the practical application of knowledge” or “manner of accomplishing a task”

Fats and oils - 344 Iodine value of an edible oil INTRODUCTION Fats and oils known as triglycerides contain long chain hydrocarbons with carboxyl groups (COOH groups). These fatty acids are classified into the number of double bonds present in the fatty acid. When the carbon atoms in these chains are bounded to the maximum possible number of hydrogen atoms‚ the triglyceride is said to be saturated. When one or more double bonds exist between carbon atoms in the chain‚ less hydrogen exists

If your goiter is due to an iodine deficiency‚ then obviously you will need to correct this deficiency. Many people with thyroid and autoimmune thyroid conditions do have such a deficiency‚ which can be determined through a 24-hour iodine loading urine test (or you can get a general idea of whether a deficiency exists through an iodine patch test). If it’s determined that you have an iodine deficiency‚ then it will be necessary to begin supplementing with iodine‚ which is what I did when I was

different juices. Iodine will be added to the juice‚ which will create a reaction that can help determine the Vitamin C content. To start‚ pour 30 milliliters (mL) of Lugol’s solution into a 500 mL graduated cylinder. Add enough distilled water to bring the level of fluid to 300 mL. Slowly pour the diluted solution into the amber glass bottles‚ using a funnel. Store the bottles in a dark place‚ keeping the bottles

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

solution by a redox titration using iodine. Vitamin C (ascorbic acid) is a water-soluble‚ essential oxidant that plays a vital role in the protection of the body from infections and disease it is acquired from primary fruits and vegetables. With the use of different materials as natural orange juice‚ Tampico (chemical orange juice) and other solutions that contain vitamin C we will find the amount of vitamin C in each of these concentrations with the help of iodine‚ and with that data we can compare
