Question

Which of the following is Barytes?
$A.$ $BaS{O_4}$
$B.$ $BaC{l_2}$
$C.$ $BaO$
$D.$ $BaC{O_3}$

Answer 1

Hint: Baryte is a white or colourless mineral that is the primary source of barium. Baryte, celestine (strontium sulphate), anglesite (lead sulphate), and anhydrite (calcium sulphate) are all members of the baryte group. Baryte is found in a variety of depositional habitats and is formed by a variety of processes, including biogenic, hydrothermal, and evaporation.

Complete Answer:
The natural ore of barium is blanc-fixe, a white colouring agent derived as a precipitate of barium sulphate $(BaS{O_4})$ from Barite. Heavily sparred is another name for it. Barytes, also known as barite, is a colourless or white mineral that is frequently tinted with yellow, red, brown, and blue. It's a rhombic crystalline system. Barytes is sometimes found as transparent crystals, but it is usually opaque. Its key characteristics are its high specific gravity $(4.5)$, poor solubility, non-toxicity, and chemical and physical inertness.

So the correct Answer is $A.$ $BaS{O_4}$ .

Additional Information:
Baryte can be found in limestone lead-zinc veins, hot spring deposits, and hematite ore. Anglesite and celestine are two minerals with which it is frequently linked. It's been found in meteorites as well. Its properties in application include minimal binder replacement, quick dispersibility, extreme fineness, low agglomerate content, and high gloss (in coatings).

Note:
Insoluble in water and aqueous alkali, barium sulphate is marginally soluble in strong acids. In water, it has a high opacity but settles rapidly, while in oil, it is more or less clear.Surface and underground mining are used to extract it, which is then processed using basic physical procedures to produce the desired size product and remove any unwanted elements.
