"Hydrated Dolomite" is a misnomer. The description provided refers to a saturated solution of calcium hydroxide, Ca(OH)₂, not a hydrated form of the dolomite mineral CaMg(CO₃)₂. The formula (OH)CaMg is incorrect for hydrated dolomite; it suggests a compound that doesn't exist in nature or as a typical industrial product. A true hydrated dolomite would involve water molecules incorporated into the crystal structure of the dolomite mineral.
The description accurately describes calcium hydroxide, Ca(OH)₂, a white powder, which is a moderately strong base. It reacts with acids, can attack some metals like aluminum, and protects others like iron and steel from corrosion. Its reaction with carbon dioxide (CO2) leads to the formation of calcium carbonate and a milky appearance. At 512°C, the partial pressure of water in equilibrium with Ca (OH)₂ reaches 101 kPa (atmospheric pressure), causing it to decompose into calcium oxide (CaO) and water.
Therefore, clarifying the terminology is crucial. The material described is not "hydrated dolomite," but rather calcium hydroxide, Ca (OH)₂, often called slaked lime or hydrated lime.
