At the end of the test, the students have the ability to identify the useful group within aldehydes and ketones, also on deciding their physical and chemical substance properties and to perform chemical type test to distinguish one from the other.
II. MATERIAL and APPARATUS
The test used a bunsen burner, vials, 100 ml beaker, test pipe holder, vial clean, clay fire shield, line gauze, acetaldehyde1, benzaldehyde2, acetone3, 2, 4-dinitrophenylhydrozine4, ammoniacal magic nitrate solution [ (Ag((NH)3)2)NO3], Fehlings a and b, 6m sulfuric acid solution [H2SO4], very dilute potassium permanganate [KMnO4], distilled drinking water [H2O] and Schiff's reagent5.
Everything existing in the nature has its mass, whether it is a tree, a stone, water or any other matter. There is a great possibility that throughout your studies in the area of chemistry you will need to deal with different chemical problems that have to do with the calculation of molar mass. Handling this task is not easy, especially for beginners, so in order to be able to cope with it, you will need to learn a lot of things, practice a lot and so on. It is necessary because this knowledge will be useful for you in the future, since such skills as calculating the molar mass are basic skills, when it comes to chemistry. Having said that, apart from practical side concerning this issue, it is also important to have needed theoretical background, as long as everything starts with the theory.
