Iodine-131 has varied uses in medicine where it is utilized as a part of atomic pharmaceutical restoratively and can likewise be seen with symptomatic scanners in the event that it has been utilized remedially.

The larger the amount of iodine in the chemical will result in a purple/black color. The iodine/starch complex has energy level spacings that are just for absorbing visible light-giving the complex its intense purple/black color. The method to be used‚ consist of three drops of iodine in the chemical filled tube that is to

peroxide reacts with iodide ions producing iodine‚ when in an aqueous acid solution. H2O2 (aq) + 2I- (aq) + 2H3O+(aq) I2 (aq) + 2H2O(l) To detect iodine you can look at the color shown by the addition of starch solution. Iodine also reacts with sodium thiosulphate solution‚ which acts as a delaying agent. Adding sodium thiosulphate to the reaction mixture will allow the iodine produced initially to react with the thiosulphate ions‚ which reduce the iodine to iodide ions‚ leaving the starch unchanged

Introduction Genetics is the science that explains the variation and transmission of inherited characteristics from parents to offspring. The basic laws of heredity became popular to science in 1865‚ with the publication of the works of Gregor Mendel‚ the father of genetics. He observed that by breeding pairs of different varieties of peas‚ the offspring resembled one of the parents. This inspired him to continue his work that resulted to more experiments on plants. Before starting this exercise

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
