Question

Cinnabar is an ore of &ndash;a)Mercuryb)Copperc)Calciumd)LeadCorrect answer is option 'A'. Can you explain this answer?

Answer

Cinnabar is a toxic mercury sulfide mineral with a chemical composition of HgS. It is the only important ore of mercury. It has a bright red color that has caused people to use it as a pigment, and carve it into jewelry and ornaments for thousands of years in many parts of the world. Because it is toxic, its pigment and jewelry uses have almost been discontinued.

Answer

Cinnabar with chemical formula of H2S is the ore of mercury.

Answer

Cinnabar is a toxic mercury sulfide( HgS ) and it is the only important ore of mercury.

Answer

Introduction to Cinnabar
Cinnabar is a significant mineral known for being the primary ore of mercury (Hg). It is composed of mercury sulfide (HgS) and has a distinctive red color, making it easily identifiable.
Properties of Cinnabar
- Chemical Composition: Cinnabar consists of mercury and sulfur, with the formula HgS.
- Appearance: It typically occurs in a vibrant red hue, which can range from bright red to dark red, and sometimes even brownish.
- Crystal Structure: Cinnabar crystallizes in the trigonal system, often forming as massive or granular aggregates.
Occurrence and Extraction
- Natural Deposits: Cinnabar is commonly found in volcanic regions where mercury is present. It can be deposited through hydrothermal processes.
- Mining Methods: Historically, cinnabar has been mined through various methods, including open-pit and underground mining, to extract mercury.
Usage of Mercury from Cinnabar
- Industrial Applications: The extracted mercury from cinnabar is utilized in several industries, including:
- Thermometers: Mercury's high thermal conductivity makes it ideal for temperature measurement.
- Batteries: Used in some types of batteries for better efficiency.
- Fluorescent Lights: Mercury vapor is used in fluorescent lighting.
- Historical Significance: Cinnabar has been used since ancient times for pigment in art and cosmetics, known as vermilion.
Conclusion
In summary, cinnabar is an essential ore for mercury, playing a crucial role in various industrial applications. Its unique properties and historical significance further underscore its importance as a mineral resource.
