Short-term Exposure: Calcium oxide causes irritation of the eyes, nose, throat, and skin. Severe burns may result from contact with this chemical.
What does calcium oxide remove?
Chemical or power production: Solid sprays or slurries of calcium oxide can be used to remove sulfur dioxide from exhaust streams in a process called flue-gas desulfurization.
What is CaO calcium oxide?
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.
What is calcium oxide used?
Uses of Calcium Oxide It is extensively used for medicinal purposes and insecticides. It finds its application in the manufacturing of cement, paper, and high-grade steel. Lime is used as a reagent in laboratories for dehydration, precipitation reaction, etc.
Is calcium oxide safe?
HAZARD SUMMARY * Calcium Oxide can affect you when breathed in. * Contact can severely irritate and burn the eyes and skin. * Breathing Calcium Oxide can irritate the lungs causing coughing and/or shortness of breath.
Is calcium hydroxide safe for skin?
Prolonged contact of the skin with calcium hydroxide may cause skip desqua- mation and a vesicular rash, skin ulceration, and cor- rosion in some cases [Parmeggiani 1983; NLM 1992). Ingestion of this material has caused severe pain, vomiting, tissue corrosion, perforation, and death.
Is calcium oxide good for health?
1) Calcium oxide dust is irritating and may be caustic to the mucous membranes of the upper respiratory tract, causing inflammation and possibly pneumonia, pulmonary edema, and/or bronchitis. Airway burns resulted from severe exposure in an industrial accident.
What is the common name for calcium oxide?
quicklime
Calcium oxide (CaO), commonly known as quicklime or burnt lime, is a widely used chemical compound.
How do you store CaO?
Conditions for Safe Storage: Store in a cool, dry, well-ventilated area. Store in a tightly sealed container.
Is calcium oxide toxic to humans?

Is calcium hydroxide cancerous?
Cancer Hazard * According to the information presently available to the New Jersey Department of Health and Senior Services, Calcium Hydroxide has not been tested for its ability to cause cancer in animals.
Can I eat limestone?
Limestone is chemically called calcium carbonate and is thus, abundantly rich in calcium. Besides this, a host of other minerals are present in it, making it suitable for good health. The practice of eating limestone with betel leaves (paan) is common in India.
What is the formula for whitewash?
CaO
Answer: The chemical substance X used for whitewashing is Calcium oxide, also known as quicklime or burnt lime or lime. Calcium oxide is an alkaline earth flux with the chemical formula CaO.
Which calcium is used for white washing?
Quicklime is used for whitewashing as it produces calcium hydroxide (CaOH) when it reacts with water (H2O) and absorbs carbon dioxide (CO2) from the environment, as a result, it produces calcium carbonate (CaCO3) which creates a hard coating on the walls.
What is quicklime used for?
Quicklime has a wide range of uses, including in the production of iron and steel, paper and pulp production, treatment of water and flue gases and in the mining industry. For the iron and steel industry, we also supply different fractions of both reactive shaft furnace-burnt and hard-burnt rotary kiln lime.
What is difference between quicklime and lime?
Quicklime is calcium oxide with the chemical formula CaO whereas, hydrated lime is calcium hydroxide with the chemical formula Ca(OH)2. This is the key difference between quicklime and hydrated lime. Furthermore, the molar mass of quicklime is 56.07 g/mol while the molar mass of hydrated lime is 74.09 g/mol.
