color change or a warming effect. Flammability was tested by igniting 3-5 drops of the sample in a small evaporating dish. Baeyer’s test and Bromine test were used for tests for active unsaturation. Aromaticity of the compound was determined through nitration. Oxidation was tested by introducing 8 drops of 2% KMnO4 solution and 3 drops of 10% NaOH solution to 4 drops of the sample organic compound in a test tube and warming the mixture through water bath. All of the test compounds are liquid and colorless

Explosives A chemical explosive is a compound or a mixture of compounds susceptible of a rapid chemical reaction causing a quick physical outburst of gases or heat radiation. The first explosives were created by the Chinese in the 11th century. These were mixtures of nitrate salts‚ sulfur and charcoal‚ now known as black powder. Gunpowder which is a low explosive‚ exhibits deflagration‚ or rapid burning‚ rather than detonation‚ the reaction exhibited by high explosives. While‚ perhaps counterintuitively

Xanthoproteic Test • The amino acids that contain benzene ring like tyrosine and tryptophan undergo nitration in this test and gives yellow colour. Millon’s Test • It is specific for tyrosine‚ the only amino acid that contain a phenol group on which a hydroxyl group is attached. It gives red precipitate. Hopkins_cole Test • It is specific

While there are many means of achieving this‚ two of the most common are prolonged boiling in a strong acid (acid-HVP) or strong base or using an enzyme such

should happen is that the nitric acid and ammonia react with the aromatic ring and gives a coloured salt compound. When Nitric acid is heated with a protein like tyrosine it gives off a yellow colour ‚or tryptophan and orange colour this is down to nitration. This is why this test is used for the presence of an activated benzene ring. The “(4) Test for sulphur”this

T2:BIOCHEMISTRY AND ANALYSIS:DETECTION OF FATS‚PROTEINS AND CARBOHYDRATES OBJECTIVE The main purpose of the experiment is to understand some general tests that detect fats‚proteins and carbohydrates in foods. INTRODUCTION Carbohydrates are also known as sacharides. There are 4 main groups of carbohydrates‚which are monosaccharides‚ disaccharides‚ oligosaccharides and polysaccharides. Carbohydrates play an important role in living organism as it is the energy storage‚ and it also plays
