Question

Write the chemical formula of quicklime and slaked lime.

Answer 1

Hint: Lime is a calcium-containing inorganic mineral that is generally made up of oxides and hydroxides, most often calcium oxide and calcium hydroxide. It's also the name for calcium oxide, which is found in volcanic ejecta as a byproduct of coal-seam fires and in altered limestone xenoliths. The name lime comes from its early use as a building mortar, and it means "sticking" or "adhering."

Complete answer:
Let us talk about QuickLime. Calcium oxide \[\left( {CaO} \right),\] sometimes known as quicklime or burnt lime, is a chemical substance that is frequently used. At room temperature, it is a white, caustic, alkaline, crystalline solid. The name "lime" refers to calcium-containing inorganic compounds that are mostly composed of carbonates, oxides, and hydroxides of calcium, silicon, magnesium, aluminium, and iron. Quicklime, on the other hand, refers to the single chemical molecule calcium oxide. Free lime is calcium oxide that has not been processed and has not reacted in building materials such as cement.
\[CaC{O_3}\] is the chemical formula for lime.
When lime is dissociated, fast lime and carbon dioxide are produced.
\[CaC{O_3}{\text{ }} \to {\text{ }}CaO{\text{ }} + C{O_2}\]
\[CaO\]is the chemical formula for quick lime.
Let us have a look at Slaked Lime. The inorganic substance calcium hydroxide (also known as slaked lime) has the chemical formula \[Ca{\left( {OH} \right)_2}\]. When quicklime (calcium oxide) is combined or slaked with water, it produces a colourless crystal or white powder. Hydrated lime is also known as caustic lime, builders' lime, slack lime, cal, and pickling lime.
Lime water or slaked lime is formed when quick lime combines with water.
\[CaO{\text{ }} + {\text{ }}{H_2}O{\text{ }} \to {\text{ }}Ca{\left( {OH} \right)_2}\]
\[Ca{\left( {OH} \right)_2}\]is the chemical formula for slaked lime.

Note:
Quicklime is a comparatively low-cost material. It is a commodity chemical, as is a chemical derivative (calcium hydroxide, of which quicklime is the basic anhydride).
Calcium hydroxide has the \[E\] number \[E526\] and is used in a variety of applications, including food preparation. A saturated solution of calcium hydroxide is known as lime water.
