why cao is called quicklime

29 30 31. chemical compound, CaO, a colorless, cubic crystalline or white amorphous substance. Quicklime, more formally known as calcium oxide (CaO), is a caustic alkaline substance that is produced by heating limestone in specially designed kilns. calcium oxide, chemical compound, CaO, a colorless, cubic crystalline or white amorphous substance. [I hope help] ... Calcium oxide that survives processing without reacting in building products such as cement is called free lime. Calcium oxide, a common chemical compound that appears as a white crystalline solid at room temperature, is easily attainable through the thermal decomposition of limestone. Calcium Oxide. This was how the material, also known as quicklime, was acquired for human use, after ancient peoples burned limestone in a kiln to take advantage of its structural properties. Quicklime is produced by heating naturally-occurring limestone rock, which contains calcium carbonate. The use of quicklime and slaked lime is much less common. Heating up calcium carbonate drives out carbon dioxide, leaving Calcium Oxide. Quicklime is a caustic compound known by its chemical name calcium oxide (CaO). Quick lime is an amorphous white solid with a high melting point of 2600 ° It is a very stable compound and withstands high temperatures. Calcium oxide is used industrially as an absorbent, in the creation of steel, in fertilizer, as a water softener and as a potential hydrogen (pH) regulator for wastewater. Calcium Oxide reacts with … It is also called lime, quicklime, or caustic lime, but commercial lime often contains impurities, e.g., silica, iron, alumina, and magnesia. Asked by Wiki User. 2010-09-12 16:39:43 2010-09-12 16:39:43. Calcium has an ionic radius of 0.099 nanometers (nm), and oxygen has an ionic radius of 0.14 nm. Problem 137P. It is prepared by heating Calcined dolomite (CaO MgO), can also be used in water treatment plants, for example to eliminate silica from water. Lime is a term that includes calcium oxide (CaO, also called quicklime) and calcium hydroxide [Ca(OH)2 also called slaked lime]. Answer. “Quick” used to be used in a sense that meant alive, as in the “quick and the dead”.) Wiki User Answered . It is also called unslaked Lime. Calcium Oxide is also called Quicklime (when water is added, it heats up and bubbles like it’s boiling, make it seem alive. This process is called the slaking of lime. Other articles where Calcium oxide is discussed: calcium: Compounds: Calcium oxide, CaO, also known as lime or more specifically quicklime, is a white or grayish white solid produced in large quantities by roasting calcium carbonate so as to drive off carbon dioxide. Why is calcium oxide called quick lime? At room temperature, CaO will spontaneously absorb carbon dioxide from the atmosphere,… Calcium oxide (CaO), also called quicklime, is an important component in cement and soda-lime glass. It is a white, caustic, alkaline, crystalline solid at room temperature. It appears as a white powder when cold, and yellow when heated. There are a wide range of uses for this substance, ranging from mortar to flux, and it has been used by humans for centuries. Properties of Calcium Oxide. It is used in the steel industry to remove acidic impurities, in air-pollution control to remove acidic oxides such as SO2, and in water treatment. Top Answer. This is because the magnesium in the dolomite acts as the main reactive agent for the elimination of silica. Calcium oxide (CaO), commonly known as quicklime or burnt lime, is a widely used chemical compound. Calcium oxide, more often known as quicklime, is a high-volume chemical used in many industries.This is because calcium oxide has many uses, is inexpensive and is easy to create.
