    I. Abstract The common organic compounds provide us with nutrients are sugars and starches‚ carbohydrates‚ proteins‚ and lipids. In this lab‚ qualitative tests are performed to identify the presence of organic compounds in food using indicators‚ chemical substances that react in a certain way when a particular substance is present. We put one indicator into the each test tube containing different solutions at a time to see what organic compound is present. The color change in the indicator tells

    In this laboratory experiment is stating that organic lipids have the ability to dissolve lipids membranes‚ and in this exercise acetone would be the main source to be used to have the reaction of dissolving the lipids inside the tubes. This exercise was to be able to observe how the chemicals reacted in rare temperatures such in heat and in cold weather‚ also this type of changes can create a new color either making the color lighter or darker. The reaction of a light color would be that it did

    objective of this experiment was to carry an organic synthesis; the preparation of salicylic acid from methyl salicylate. To do an organic synthesis‚ it is needed to chemically modify the molecules of another compound to end up with the desire compound. Methyl salicylate is the major constituent of wintergreen oil‚ which is why it was used in this experiment as the starting material. The new technique used in this experiment is heating under reflux. Many organic compounds‚ when heated become volatile and
