The spelling of the Latin phrase "calx viva" may seem unusual to English speakers, but it makes sense in the context of Latin pronunciation. The first word, "calx," is pronounced /kalks/ with a hard "k" sound and a leading "a" that's pronounced like "ah." The second word, "viva," is pronounced /ˈwiːwa/ with a long "i" sound and emphasis on the second syllable. Together, the phrase means "live lime" and is often used as a technical term in chemistry and other fields.
Calx viva is a Latin term that translates to "living lime" in English. It is a chemical compound that refers to quicklime or calcium oxide, a white, caustic, alkaline crystalline solid. Calx viva is obtained by heating limestone or calcium carbonate at high temperatures in a process called calcination.
In its natural state, calcium carbonate exists in the form of limestone or chalk. When subjected to intense heat, such as in a kiln, the limestone decomposes, releasing carbon dioxide and leaving behind calcium oxide. This resulting substance is calx viva, which is widely used in various industries for its diverse properties and applications.
Calx viva is highly reactive and can react vigorously with water, releasing heat and transforming into calcium hydroxide or slaked lime. This exothermic reaction is often used in construction as it enables the formation of strong bonds, creating durable and resilient structures. Calx viva is also utilized in agriculture, wastewater treatment, and as an additive in various products, such as cement, mortar, and plaster.
Furthermore, calx viva is known for its ability to neutralize acidic substances due to its alkaline nature. This property makes it indispensable in industries that require pH control in processes like water treatment, pharmaceutical productions, and metallurgical applications. It is worth noting that proper handling and precautions are necessary while working with calx viva due to its corrosive and caustic properties.
