INTRODUCTION: Carbohydrates are the product that made up from carbon‚ hydrogen and oxygen. Carbohydrates are form by the combination of carbon dioxide and water molecules. The carbohydrates contain two specific functional group in it which is the hydroxyl groups and carbonyl groups.A reducing sugar is a type of sugar with is an aldehyde group.This means that sugar can act as a reducing agent.The procces of reducing sugar is isomerisation‚example of reducing sugar islactose

The Fukushima Nuclear Power Plant accident caused ecological problems. Abstract The Fukushima nuclear accident triggered a large-scale nuclear leak‚ which has had an immeasurable impact on the global ecological environment. This article addresses‚ in depth‚ features of the Fukushima Nuclear Power Plant accident: during the incident‚ the impact of the incident‚ and aspects of the aftermath. Through an analysis of the Fukushima Nuclear Power Plant accident‚ certain referential and significant

pH of 7. In the experiment I have used buffer solutions with the pHs of 2.8‚ 4 and 6.5. I have also used iodine and starch. Normally‚ iodine is orange-yellow‚ however when you add starch to it‚ the solution will turn blue-black. Aim: The aim for this experiment is to investigate how the different buffer solutions work on the enzyme amylase. This will be investigated by using iodine and by timing the experiment using the colorimeter and the program Loggerlite. Hypothesis: The pH

chemical tests‚ such as solubility‚ pH‚ or color tests. In our group we had to test come common powders such as Alka-Seltzer‚ baking soda‚ flour‚ Vitamin C (ascorbic acid)‚ and salt. Other chemicals that were used to do this experiment were vinegar‚ and Iodine 2 Solution. The equipment used to do this experiment was red litmus paper‚ and 5 test tubes per group. After all materials were gathered‚ we then had to do five different tests to determine what the powder material does. The first test was to

Who Took Jerell’s iPod? Lab Purpose: Standardized Tests The purpose of testing the organic nutrients (vegetable oil‚ glucose‚ starch‚ powdered egg white) with each of the different indicators (brown paper towel‚ benedicts‚ iodine‚ biurets) was to determine the color it would turn with positive traces of the nutrient. The purpose of testing just the Distilled H2O was to determine the color it would turn with negative traces. Nutrient in the Different Foods The purpose of testing each of the

Water and IKI was in jar and the iodine caused the color change of the water. 5. Why did a color change occur in the dialysis tubing bag? In the bag there was water‚ sugar (glucose) and starch. When IKI (iodine) comes into contact with the starch the contents in the bag turned blue. This IKI was able to
