Zinc Carbonate Formula

Zinc Carbonate Formula

Zinc nano powder has a wide range of applications such as rubber manufacturing, respiratory system and cosmetics. Powder size has a great impact on material performance. Finally, zinc carbonate use is likely to increase in the future due to the rapid growth of cosmetics, rubber, and agriculture.

Zinc Carbonate Formula, commonly known as smithsonite, calamine, or zinc spar, is a white, crystalline powder. Physicist James Smithson provided the inspiration for the name. It is zinc ore and the formula for zinc carbonate is ZnCO3. It is a crystalline solid, submicron or nanopowder, white, odorless, insoluble in water, alcohol, or acetone, but slightly soluble in ammonia. Soluble in alkalis and acids. Zinc carbonate is a major source of zinc because it can be easily converted to other zinc compounds, such as zinc oxide. Heating is used to complete the process, resulting in the formation of zinc oxide and carbon dioxide. Firing is another name for this process. Rapidly expanding applications such as cosmetics, agriculture, and rubber production have increased the demand for zinc carbonate. Zinc Carbonate Formula can be synthesized in various ways depending on its application, production scale, and structure.

Preparation of Zinc Carbonate

A soluble zinc salt such as zinc sulfate is combined with the sodium carbonate solution. Zinc carbonate (insoluble and forms a white precipitate) and sodium sulfate (extremely soluble, so it stays in solution) are the final products. ZnSO4 (aq) + Na2CO3 (aq) → Na2SO4 (aq) + ZnCO3 (s)

Since zinc is an amphoteric element, its oxides dissolve in strong alkaline solutions to form zincates.

 ZnO + H2O + 2NaOH → Na2Zn(OH)4

Zinc Carbonate Formula can also be produced by reacting zincate with CO2.

 Na2Zn(OH)4 + 2CO2 → Na2CO3 + ZnCO3 + 2H2O

Zinc Carbonate Properties

The Physical and Chemical properties are mentioned below:

Physical Properties of Zinc Carbonate

The molecular weight of Zinc Carbonate Formula is 125.38 g/mol. The boiling point of zinc carbonate is 333.6 degrees Celsius. The melting point of zinc carbonate is 1970 degrees Celsius. The density of zinc carbonate is 3.5 g/cm3. It is a white powder with a slight vinegar odour. Since it is basic in nature, it has a pH of 10 or higher and not soluble in water. 

Chemical Properties of Zinc Carbonate

Carbon dioxide gas is released when zinc carbonate combines with acid to form zinc chloride.

 When zinc carbonate undergoes a decomposition reaction, zinc oxide is produced and carbon dioxide gas is generated. 

Zinc Carbonate Uses

Use of Zinc Carbonate Formula is an inorganic salt widely used as a catalyst for organic synthesis reactions. It is a suitable precursor for the production of zinc oxide particles. It is widely used in the rubber industry as a raw material. These two materials are quite similar in refractive index, so they are added to improve the light transmission or transparency of natural rubber. It is used in a wide range of products including bath, makeup, body care, shaving, oral care, skin & hair care. It is also used as a raw material for feed additives. Zinc Carbonate Formula deficiency can limit animal growth, as it plays an important role in bone formation. Zinc Carbonate Formula, a sulfur absorber, is also used in the petroleum industry. Used as an astringent and absorbent for dusting inflamed areas. Due to its antiseptic properties, it is often used in medicine. 

Sample Question

Question 1: What are the uses of Zinc Carbonate Formula?

Answer: Commonly used as an anti-corrosion barrier for steel. Zinc carbonate is found in a wide variety of materials, colour pigments and agricultural products. Zinc anodes, often known as batteries, are used in a variety of applications such as appliances, TV monitors, and lighting. 

Question 2: What are the properties of Zinc Carbonate Formula?

Answer: Zinc Carbonate Formula, like other carbonates, readily dissolves in acidic solutions due to its basic nature, but is insoluble in water. Carbon dioxide is produced in the process. In very strong bases, this too will dissolve and form a zincate. Zinc carbonate can be thermally decomposed to produce zinc oxide.
