How do we obtain chlorine?

Common salt is sodium chloride, NaCl. It can be made in a laboratory by the reaction of sodium with chlorine. However, it is found naturally in large amounts in sea water or in underground deposits. It is often obtained either by evaporating sea water or by mining underground deposits.

Moreover, how do you make chlorine gas?

Gas extraction. Chlorine can be manufactured by electrolysis of a sodium chloride solution (brine). The production of chlorine results in the co-products caustic soda (sodium hydroxide, NaOH) and hydrogen gas (H2). These two products, as well as chlorine itself, are highly reactive.

How can carbon dioxide be collected?

The gas produced in a reaction is bubbled through a trough of water and into an upturned gas jar filled with water. This works well for insoluble gases such as hydrogen, or gases that do not dissolve easily in water, such as oxygen and carbon dioxide.

Why should chlorine be used in a fume cupboard?

This kills any harmful bacteria in the water, making it safe to drink. Chlorine is also added to the water in swimming pools. Because the halogens are very reactive and poisonous, care must be taken when using them. Chlorine is used only in a fume cupboard.

How chlorine gas is made?

Gas extraction. Chlorine can be manufactured by electrolysis of a sodium chloride solution (brine). The production of chlorine results in the co-products caustic soda (sodium hydroxide, NaOH) and hydrogen gas (H2). These two products, as well as chlorine itself, are highly reactive.

What is the use of chlorine gas?

A yellowy-green dense gas with a choking smell. Chlorine kills bacteria – it is a disinfectant. It is used to treat drinking water and swimming pool water. It is also used to make hundreds of consumer products from paper to paints, and from textiles to insecticides.

How do you get chlorine out of your eyes?

Rinse your eyes with cool water. After swimming, residue from the water may remain in your eyes, and rinsing them with cool water will wash away traces of chloramines or other substances that may be causing irritation. Hold your face over a sink and slowly pour water from a cup into one eye, then the other.

How chlorine gas is produced?

Chlorine is produced by passing an electric current through a solution of brine (common salt dissolved in water). This process is called electrolysis. The chemical term for salt is sodium chloride (NaCl). Essential co-products are caustic soda (sodium hydroxide or NaOH) and hydrogen (H2).

What makes chlorine gas?

Chlorine gas is a pulmonary irritant with intermediate water solubility that causes acute damage in the upper and lower respiratory tract. Mixing of chlorine bleach (sodium hypochlorite) with ammonia or acidic cleaning agents is a common source of household exposure.

Is bleach made from chlorine?

Chemically speaking, chlorine bleach is a water solution of sodium hypochlorite. Common household laundry bleach, used to whiten and disinfect laundry, is typically either 5.25 percent (“regular strength”) or 6 percent sodium hypochlorite (“ultra strength”).

How is chlorine used?

Chlorine is commonly used as an antiseptic and is used to make drinking water safe and to treat swimming pools. Large amounts of chlorine are used in many industrial processes, such as in the production of paper products, plastics, dyes, textiles, medicines, antiseptics, insecticides, solvents and paints.

What is the main purpose of chlorine?

Chlorine kills pathogens such as bacteria and viruses by breaking the chemical bonds in their molecules. Disinfectants that are used for this purpose consist of chlorine compounds which can exchange atoms with other compounds, such as enzymes in bacteria and other cells.

Is chlorine gas man made?

This table regroups all today’s known elements, natural ones and man-made elements. Chlorine is special: it is so highly reactive that in nature you will hardly find it in its pure, molecular form as chlorine gas (Cl2). But thousands of chlorinated chemical compounds exist, natural ones and compounds produced by man.

Where chlorine is found?

Chlorine can be found in abundance in both the Earth’s crust and in ocean water. In the ocean, chlorine is found as part of the compound sodium chloride (NaCl), also known as table salt. In the Earth’s crust, the most common minerals containing chlorine include halite (NaCl), carnallite, and sylvite (KCl).

How is chlorine formed in nature?

In nature it is only found combined with other elements chiefly sodium in the form of common salt (NaCl), but also in carnallite, and sylvite. Chlorides make up much of the salt dissolved in the earth’s oceans: about 1.9 % of the mass of seawater is chloride ions.

How do they make caustic soda?

The electrolysis process produces 2.25 tonnes of 50% caustic soda with each tonne of chlorine. The primary raw material is common salt, usually in the form of underground deposits which are brought to the surface as a solution in a pumped high pressure water supply. The sodium chloride solution is often called brine.

What countries produce chlorine?

Chlorine. As much as 60% of industrial chemicals produced rely on the manufacture of chlorine in some way. In the UK over 1.6 million tonnes of chlorine are produced annually, with some 44 million tonnes being produced worldwide. Other chlorine producers include the United States, Canada, Brazil, Japan, China and India

How is chlorine mined?

Chlorine is obtained by the electrolysis of sodium chloride solutions. Along with sodium, chlorine is abundant in the oceans. The most common chlorine-bearing mineral is, of course, halite (sodium chloride). Halite salt is mined in the USA, China, Germany, Russia and Canada.

How do they make chlorine bleach?

The raw materials for making household bleach are chlorine, caustic soda, and water. The chlorine and caustic soda are produced by putting direct current electricity through a sodium chloride salt solution in a process called electrolysis.

How is sodium chloride used?

In its edible form of table salt, it is commonly used as a condiment and food preservative. Large quantities of sodium chloride are used in many industrial processes, and it is a major source of sodium and chlorine compounds used as feedstocks for further chemical syntheses.

How sodium is extracted from its ore?

Sodium is extracted from molten sodium chloride in a Down’s cell. The sodium chloride is mixed with calcium chloride to lower its melting point. The two elements are kept apart by a steel gauze in the cell. An ore is a rock containing a metal or metal compound from which it is economically viable to extract the metal.

What is sodium chloride used to treat?

Sodium chloride is the chemical name for salt. Sodium is an electrolyte that regulates the amount of water in your body. Sodium also plays a part in nerve impulses and muscle contractions. Sodium chloride is used to treat or prevent sodium loss caused by dehydration, excessive sweating, or other causes.

What is chlorine in the pool?

Liquid Chlorine is called Sodium Hypochlorite (NaOCl), and because it is already in solution, ‘sodium-hypo’ produces hypochlorous acid instantly when it contacts water. The liquid can be poured directly into the pool but it is recommended to use a diaphragm pump or a peristaltic pump to inject it into the plumbing.
