1. OBJECTIVE
Evaluate the oxidizing nature of halogens (column 17 or 7A) of the periodic table. To do this, chemical reactions of substances containing halogens will be carried out inside the hood.
At the end of this experiment, you should be able to:
experimentally verify some properties of halogens;
identify the oxidizing tendency of halogens.
2. WHERE TO USE THESE CONCEPTS?
The concepts covered in this practice explore the oxidizing nature of halogens, that is, they highlight the ease with which these elements tend to gain electrons. This property is very important for industrial use. For example, elements such as chlorine and fluorine are used in water treatment; The iodine present in table salt helps prevent diseases. bromine is used, among other applications, in the photographic development process.
3. THE EXPERIMENT
The reactions will be carried out in test tubes inside the hood. The reagents will be mixed using a Pasteur pipette.
4. SECURITY
In this practice, gloves and a lab coat, mask and glasses will be used.
5. SCENARIO
The environment features an exhaust hood, where the experiment will take place, along with the test tubes and solutions that will be in the hood cabinet.
