Chlorine-

Chlorine is a chemical element on the periodic table of elements that has a wide range of applications in various fields of science and technology. This article will discuss the range of uses of chlorine and its role in various areas.

Use of chlorine in industry. Chlorine is one of the most common chemical reagents in industry and is widely used to produce various compounds, including chloride salts, acids, alcohols and organic compounds. Due to its chemical properties and ease of production, chlorine is widely used in the production of pulp, rubber, plastics, paints and other products. It is also an important reagent in the metallurgy and steel industries, where it is used to purify alloys and metals.

Chlorine also plays an important role in the environmental purification of water and air. Ozonation of water using chlorine is an effective method of purifying water from harmful substances that can cause disease. Ozone is also used to remove toxic gases and vapors from the air, making it a useful tool for combating environmental pollution. In addition, chlorine has many uses in the pharmaceutical industry, such as in the production of antibiotics and hormones.

Chemical properties of chlorine. Chlorine has unique chemical properties that make it indispensable in various industries. It is a colorless and odorless gaseous substance with a density of 3.2 g/l at a temperature of 0 degrees Celsius. Chlorine is reactive and easily reacts with metals, acids and alkalis, forming the corresponding chlorides or chlorination products. For example, when chlorine is mixed with hydrochloric acid, hydrochloric acid (HCl) is formed. Chemical processes involving chlorine require strict adherence to safety regulations, as it is highly toxic. Typically, chlorine is stored in steel tanks and transported in high-pressure cylinders.

Biological effects of chlorine. Some researchers are studying the biological effects of chlorine on humans and animals. Low concentrations of chlorine usually have no harmful effects on the body, but high concentrations can cause poisoning. Symptoms of chlorine poisoning include coughing, choking, nausea, vomiting, sweating and impaired consciousness. Inhaling chlorine vapor may cause bronchospasm and other respiratory problems. The World Health Organization estimates that the lethal dose of poisoning for adults is about 70 kilograms of chlorine, which can be obtained by inhalation through the mouth of a coal stove.
