Investigating the effects of changing concentration: iodine clock reaction. Abstract This is an experiment to show the Iodine Clock Reaction. To create a chemical reaction to see how long it takes for solution to change to a dark blue Color. When changing the concentration of the iodide (K1) and adding distill water to make it up to 5cm³ each time. This is to see if the reaction takes less with less concentration or faster with more concentration added to the peroxodisulphatee. So with the solution

culture and personality. Benedict studies different cultures such as the Zuni tribe and the Dobu Indians. Each culture she finds is so different and distinctive in relation to the norm of our society. Each difference is what makes it unique. Benedict compares the likenesses of culture and individuality‚ "A culture‚ like an individual‚ is a more or less consistent pattern of thought or action" (46)‚ but note‚ they are not the same by use of the word‚ "like." Benedict is saying that figuratively

DIFFERENT RELATIONSHIPS THAT CONCENTRATION AND TEMPERATURE HAVE ON THE RATE OF REACTION Aim To study the effect that temperature and concentration of iodide ion solution have on the rate of iodide ion I⁻ oxidation by peroxodisulphate ion S₂O₈⁻‚ creating an iodine clock reaction. Introduction I decided to choose as the topic for my investigation the rate of reaction for its vital importance in the human body. Indeed I am really interested in Biology and especially physiology and I would like to study

Pepin III initiated the usage of the silver coin. As European exploration of foreign lands intensified during the sixteenth century‚ silver earned a high-ranking position on the global market as one of the most economically valuable natural resources in the world. The availability of silver increased and its popularity prompted the opening of new European and South American mines. As more mines were established‚ European governments started to issue larger silver coins‚ lessening the usage of gold

Sometimes the deeds that make one man a villain are given more weight than deeds that might deem the same man a hero. That is what happened to Benedict Arnold‚ his actions during the American Revolutionary War ensured victory for the American forces. But his acts of heroism have since been overshadowed by his final act of betrayal. When we think of the American Revolutionary War we have a tendency

Iodine is an element that is critical for normal function of the thyroid gland‚ which is a key regulator of the body’s basic metabolic rate. Iodine is a micronutrient‚ meaning we require only small amounts of it. For example‚ adults need about 150 micrograms of iodine in the form of iodide ion per day. However‚ an insufficient supply of iodide via diet and drinking water causes the non-cancerous enlargement of the thyroid gland known as goiter. Prolonged lack of iodide can lead to loss of thyroid

INTRODUCTION Iodine deficiency disorders are still very much prevalent in the world today. Two billion people‚ estimated by the WHO‚ still lack a sufficient level of iodine in their diets which leads to a range of disorders known as iodine deficiency disorders (IDD). So what is iodine? Iodine is an essential micronutrient in the diet which is used by the thyroid gland (located in the throat) to produce thyroid hormones which help control the body’s metabolism. The two most important thyroid
