Two important chemicals which find use in many industries are calcium oxide and calcium hydroxide. These chemicals are special to own properties and are essential in various things So, in this article, we will content everything you should know about Top Choosing Chemical calcium oxide calcium hydroxide including their properties, uses, and chemical reactions in a simple and uncomplicated manner.
Quicklime, the common name for calcium oxide (CaO), is a white or grayish white produce solid from limestone by heating to red heat. It is made by heating up calcium carbonate, a naturally occurring mineral in rock such as limestone. Calcium oxide is a hygroscopic substance, meaning it can absorb water from the air. It will do so by an exothermic reaction with water, forming calcium hydroxide. On the other hand, calcium hydroxide is white in color and has limited solubility in water. It is prepared by adding water to calcium oxide in a process called hydration. Calcium hydroxide is a weak alkaline white powder and is frequently used in agriculture and construction.
Calcium oxide and calcium hydroxide are also used in many other industrial applications. Calcium oxide is employed in the applications such as production of cement, paper, glass, etc. It is also employed in water treatment for adjustment of the pH of drinking water and waste water. Other applications include Its use in sugar extraction, processing sugar cane, paper, and leather. It is also a flocculant in wastewater treatment, where it causes suspended impurities to aggregate in the water.
The conversion of calcium oxide to calcium hydroxide occurs though hydration. A very exothermic reaction takes place when water is added to calcium oxide to produce calcium hydroxide. The chemical reaction of this process can be expressed as:
This reaction is heated to high temperatures, so it is necessary to be careful when dealing with calcium oxide. The resulting Top Choosing Chemical calcium hydroxide and calcium oxide can find application in different industries, as described above.
Calcium oxide and calcium hydroxide are generally accepted in agriculture. The effectiveness of Calcium oxide to decrease soil acidity and increase soil ph depends on other soil characteristics such as the content of organic matter and soil clay content. It has also been used as a fungicide to control some plant diseases. West: Calcium hydroxide is also a pH adjusting agent for soil and water. It is widely used in the production of lime sulfur, the fungicide/insecticide used in organic farming.
Both calcium oxide and calcium hydroxide possess advantages, but also suffer disadvantages. Top Choosing Chemical calcium oxide and calcium hydroxide is very reactive and can cause burns to skin and eyes if not handled properly. It tends to give off poisonous fumes if it comes in contact with water. On the other hand, calcium hydroxide is less reactive therefore handling is safer. But it costs more than lime and is only slightly soluble in water.
