Solution: The equation for the conversion of quicklime (CAO), hydrated lime (CA(OH)) and limestone (CACO) is as follows.
1. The reaction equation of quicklime to mature lime.
cao+h₂o=ca(oh)₂
2. The reaction equation of hydrated lime to limestone.
ca(oh)₂+co₂=caco₃+h₂o
3. The reaction equation of limestone conversion into quicklime.
caco₃=cao+co₂

Quicklime is ca, slaked lime is ca(oh)2, and the main component of limestone is caco3cao+h2o=ca(oh)2
Ca(OH)2+CO2=CaCO3+H2OCAco3=CaO+CO2 The reaction conditions are high temperature.

Quicklime: cao
Hydrated lime: Ca(OH)2
Limestone main component: caCO3
Quicklime to hydrated lime: CaO+H2O=Ca(OH)2Hydrated lime to limestone: Ca(OH)2+CO2=CaCO3 +H2O Limestone to quicklime: CaCO3=(heating)=CaO+CO2
-
Quicklime is converted to hydrated lime: CaO+H2O=Ca(OH)2
Hydrated lime is converted to limestone: Ca(OH)2 + CO2 = CaCO3 + H2O
Conversion of limestone to quicklime: CaCO3 = (heating) = Cao + CO2

All are white solids.
Quicklime: cao
Hydrated lime: Ca(OH)2
Limestone: caco3
cao+h2o=ca(oh)2
The reaction emits a lot of heat.
Ca(OH)2 + CO2 = CaCO3 + H2O This reaction can be used to test carbon dioxide.
CaCO3 == High temperature == Cao + CO2
Industrially produced CO2
CaCO3+2HCl=CaCl2+H2O+CO2 CO2 is produced in the laboratory

Summary. Dear, I am glad to answer your questions I am Mr. Xiaomu The chemical formula of hydrated lime is CA (OH), commonly known as hydrated lime, slaked lime, and the aqueous solution is called clarified lime water. Calcium hydroxide has the universal properties of alkali and is a strong base.
Calcium hydroxide is a binary strong base, but it is only slightly soluble in water. Calcium hydroxide has a wide range of applications in industry. Dear, remember to wear a mask and pay attention to protection to protect yourself when you go out during the epidemic

Hydrated lime refers to calcium hydroxide, the chemical formula is Ca(OH)2, commonly known as hydrated lime or slaked lime.
A white powdery solid, after adding water, it is divided into two layers, the upper layer of aqueous solution is called clarified lime water, and the lower layer of suspension is called lime milk or lime slurry. The upper base layer of clear liquid lime and hail can be used to test carbon dioxide, and the lower layer of turbid liquid lime milk is a building material.
Calcium hydroxide is a strong alkali, which has the ability to kill bacteria and antiseptic, and has a corrosive effect on ** and fabrics. Calcium hydroxide has a wide range of applications in industry. It is commonly used as a building material, and is also used as a fungicide and chemical raw material, etc.
The packaging should be intact and the loading should be secure when it is shipped. During the transportation process, it is necessary to ensure that the container does not leak, collapse, fall or damage. It is strictly forbidden to mix with flammable or combustible materials, acids, edible chemicals, etc. Not suitable for transportation in rainy weather.
Store in a cool, ventilated warehouse. The humidity in the warehouse is the most wanton, and the best is not more than 85%. It is necessary that the packaging is well sealed to avoid moisture absorption. It should be stored separately from flammable (combustible) materials and acids, and should not be mixed. The storage area should be equipped with appropriate information to contain the spillage.
Calcium hydroxide, the product of reaction with water, is alkaline and corrosive.
Calcium hydroxide is a slightly soluble substance, but when carbon dioxide reacts with calcium hydroxide, the dissolution of calcium hydroxide will be reduced, in order to achieve dissolution equilibrium, this will make calcium hydroxide move in the direction of dissolution, carbon dioxide has been reacting with calcium hydroxide, and the product is a precipitate, so as long as there is carbon dioxide, the reaction will continue, so there will be a large number of white precipitate generation.
To give you a 2009-2010 lime kiln status analysis.
1) Surface cracks and bursts.
Crack refers to the appearance of fine cracks on the surface of the green body when it is stationary, mainly due to the large temperature difference between the upper and lower parts of the body, and the expansion and cracking of the surface due to the rise of internal temperature and increased pressure, which can be found from the following factors: a Check the lime quality, too much powder ash or over-burned ash. b Room temperature is too low. >>>More
First of all, the main ingredient of lime water is calcium hydroxide. >>>More
