Iron Man: The Real Hero In today’s society‚ the concern of people and laws are not about doing good but rather having the appearance of good. People no longer care about what they need to stand for‚ only that they look like they aren’t sitting down.

Iron plays a key role in maintaining the body. It is used in the production of hemoglobin‚ a protein found in red blood cells‚ which transports oxygen to muscles and tissues throughout the body. On the other hand‚ too much iron is detrimental and can cause various significant diseases. C282Y and H63D are mutations found on the HFE gene and are the major cause of inherited iron overload (hereditary hemochromatosis). As a result‚ iron regulation is disrupted and too much iron is absorbed from a strong

Laboratory Report: Experiment 3 Analysis of commercial vitamin C tablets Name: Cheung Chun Hin‚ Harry Class: 6L (12) Date: 14-10-2009 Objective: To determine the content of vitamin C in commercial tablets (redox titration and back titration) Principle of method: Vitamin C‚ which is ascorbic acid‚ reacts with iodine rapidly in an acidic medium. C6H8O6 (aq) + I2 (aq) C6H6O6 (aq) + 2H+(aq) + 2I- (aq) Since iodine dissolves slightly in water‚ ascorbic acid cannot be titrated

copper sulfate (blue crystals)‚ sodium chloride (salt)‚ and iron. Copper sulfate is a chemical compound which is produced commercially by reacting various copper (II) compounds with sulfuric acid [1]. It generally appears as a bright blue or green crystal [1]. Its chemical formula is CuSo4. Iron is silver-white magnetic metallic and readily rusts in moist air [3]. Its chemical formula is Fe. The chemical reaction was demonstrated by the iron reacting to the copper sulfate.
