FAQs on Formation of Sodium Chloride - Acids, Bases & Salts Video Lecture - Class 10

1. How is sodium chloride formed?

Ans. Sodium chloride is formed through a chemical reaction between sodium (Na) and chlorine (Cl). During this reaction, sodium loses an electron and forms a positive ion (Na+), while chlorine gains an electron and forms a negative ion (Cl-). These ions then attract each other due to their opposite charges, resulting in the formation of sodium chloride (NaCl).

2. What are the properties of sodium chloride?

Ans. Sodium chloride is a white crystalline solid with a high melting and boiling point. It is highly soluble in water and forms a clear, salty solution. It is odorless and has a characteristic salty taste. Sodium chloride is a good conductor of electricity when dissolved in water or melted.

3. What are the uses of sodium chloride?

Ans. Sodium chloride has several uses in various industries and everyday life. It is commonly used as table salt for seasoning and preserving food. It is also used in the production of chlorine, which is essential for water purification, disinfection, and the manufacturing of various chemicals. Moreover, sodium chloride is used in the production of plastics, soaps, dyes, and textiles.

4. How is sodium chloride obtained?

Ans. Sodium chloride is obtained from various sources. It can be extracted from underground salt deposits through mining or by evaporating seawater. In the mining process, salt deposits are blasted, crushed, and then purified to obtain pure sodium chloride. On the other hand, seawater is evaporated using solar or mechanical means, leaving behind salt crystals that can be further processed to obtain sodium chloride.

5. Is sodium chloride safe for consumption?

Ans. Sodium chloride, commonly known as table salt, is safe for consumption in moderate amounts. It is an essential nutrient that our bodies require for various functions, including maintaining proper fluid balance and nerve function. However, excessive consumption of sodium chloride can lead to health issues such as high blood pressure. It is important to consume it in moderation and be mindful of the overall sodium intake from various sources.
