The Iodine Clock Investigation Introduction This is an investigation into the rate of a reaction and the factors that contribute to how fast a reaction will take place. Through the recording and analysis of raw data‚ this investigation also allows us to apply generally accepted scientific rules and to test them against results gained from accurate experimental procedures. Aim The aim of this experiment is to investigate the rate at which iodine is formed when the concentration

Investigative question: how are esters formed ? Esters are formed by the reaction of an alcohol and a carboxylic acid‚ usually in the presence of sulphuric acid to catalyse the process‚ or by the reaction of an acyl chloride with a carboxylic acid (this requires no catalyst and is irreversible without additional reactants) are the most common ways used. Others include reactions of certain molecules such as structural rearrangement. Apparatus: Plastic dropping pipettes‚ Beaker (100 cm3 or 250

111 Iodine Description: Is a trace mineral that your body uses in small amounts to synthesize thyroid hormones that are necessary for regulating the body growth‚ development‚ metabolism and body temperature. Most of the iodine in the body is found in the thyroid gland‚ but is found also in the blood and muscles. The body contains approximately 20 to 30 mg of iodine which is mostly stored in the thyroid gland located in front of the neck. Food sources: Milk is the major source‚ fish from the sea

this experiment was to use Iodine‚ Benedict and Biuret to test the reaction of the following 12 samples: 1% glucose‚ 0.3% glucose-1-phosphate‚ 1% maltose‚ honey‚ 1% sucrose‚ 1%lactose‚ 1% glycogen‚ 1% starch‚ protein‚ beer‚ distilled water and an unknown solution (test tube: 300). The iodine test for starch was to test how would starch reacted if we put iodine in it. The color of starch before the test was clear. The color of the iodine was brown. When you added iodine into starch‚ the result was

contrary - “In theory and in practice‚ it always works.” This term may indeed hold in itself a somewhat ambiguous undertone‚ and lead to confusion and misuse. Let’s look at the origin of the word; according to an etymology dictionary‚ theory derives from the Greek “theoréo” which means ‘to look at’‚ ‘to observe’. The definition tells us that one must firstly observe a phenomenon so that a theory about a certain aspect of it could form. There are essentially three forms of theories‚ and although they
