Calcium selenite - Introduction
Calcium selenite is a chemical substance whose chemical formula is Ca(HSeO3)2. The following is a description of the nature, use, preparation and safety information of Calcium selenite:
1. nature: Calcium selenite is colorless crystal or white crystalline powder. It is easily soluble in water and the solution is weakly acidic. The Calcium selenite is oxidizing and can react with a reducing agent.
2. use: Calcium selenite in chemical laboratory often used as raw materials for the preparation of sodium hydrogen selenate. In addition, Calcium selenite are also used to prepare other selenides, such as cadmium selenide and lead selenide. In certain industrial processes, Calcium selenite can be used as oxidizing and decolorizing agents. In addition, in the field of medicine, Calcium selenite are also used as antibacterial and antifungal agents for external use.
3. preparation method: Calcium selenite can be formed by the reaction of Ca(OH)2 and selenic acid (H2SeO3). First, Ca(OH)2 is dissolved in water, then selenic acid is slowly added to the solution, and finally the Calcium selenite can be obtained by filtration and crystallization.
4. safety information: Calcium selenite is not dangerous under normal circumstances, but still need to pay attention to the following safety matters: avoid direct contact with skin and eyes, when using to wear chemical protective gloves and goggles. If you have accidentally touched or inhaled Calcium selenite, rinse immediately with water and seek medical help. In addition, Calcium selenite should be stored in a dry, well-ventilated place, away from fire and flammable substances.
