What compound has an element combined with chlorine?
sodium chloride
Two of the most familiar chlorine compounds are sodium chloride (NaCl) and hydrogen chloride (HCl). Sodium chloride, commonly known as table salt, is used to season food and in some industrial processes. Hydrogen chloride, when mixed with water (H2O), forms hydrochloric acid, a strong and commercially important acid.
Is chlorine an essential element?
The essential mineral elements are: Nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, boron, chlorine, iron, manganese, zinc, copper, molybdenum, and nickel. Cations and anions, based on the positive or negative charge on the ionic form of the element as it is absorbed by plant roots.
What are the components of chlorine?
Natural chlorine is a mixture of two stable isotopes: chlorine-35 (75.53 percent) and chlorine-37 (24.47 percent). The most common compound of chlorine is sodium chloride, which is found in nature as crystalline rock salt, often discoloured by impurities.
What is chlorine used for in everyday life?
Chlorine has a variety of uses. It is used to disinfect water and is part of the sanitation process for sewage and industrial waste. During the production of paper and cloth, chlorine is used as a bleaching agent. It is also used in cleaning products, including household bleach which is chlorine dissolved in water.
How is chlorine formed?
Most chlorine is manufactured electrolytically by the diaphragm, membrane, or mercury cell process. In each process, a salt solution (sodium or potassium chloride) is electrolyzed by the action of direct electric current which converts chloride ions to elemental chlorine….Chlorine Manufacture.

How does chlorine and sodium form compounds?
When a sodium atom transfers an electron to a chlorine atom, forming a sodium cation (Na+) and a chloride anion (Cl-), both ions have complete valence shells, and are energetically more stable. The reaction is extremely exothermic, producing a bright yellow light and a great deal of heat energy.
What is a compound made up of sodium and chlorine?
Chemically, table salt consists of two elements, sodium (Na) and chloride (Cl). Neither element occurs separately and free in nature, but are found bound together as the compound sodium chloride.
Who was the first person to produce chlorine?
In 1810, the English chemist Humphry Davy proved it was an element. Since it combines directly with nearly every element, chlorine is never found free in nature. Chlorine was first produced by Carl Wilhelm Scheele, a Swedish chemist, when he combined the mineral pyrolusite (MnO 2) with hydrochloric acid (HCl) in 1774.
How is the element chlorine used in everyday life?
The Element Chlorine. 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. Two…
Which is the correct definition of combined chlorine?
2. Combined chlorine residual is the chlorine that exists in water in chemical combination with ammonia or other organic nitrogen compounds. 3. Total chlorine residual is the total amount of free and combined chlorine existing in water.
How did the element chlorine get its name?
Today, most chlorine is produced through the electrolysis of aqueous sodium chloride (NaCl). From the Greek word chloro, greenish yellow. Discovered in 1774 by Scheele, who thought it contained oxygen. Chlorine was named in 1810 by Davy, who insisted it was an element.
