What is the chemical formula for common salt?
KCl
NaCl
Na2CO3
NaOH
NaCl
Common salt is chemically known as sodium chloride, which is represented by the formula Na┬аCl. It is an essential ionic compound widely used in daily life and various chemical industries.
Common salt is chemically known as sodium chloride, which is represented by the formula Na┬аCl. It is an essential ionic compound widely used in daily life and various chemical industries.
Think of sodium and chlorine ions like microscopic magnets of opposite poles; when they meet, they snap together tightly to form a rigid, orderly crystal structure.
Na for Sodium, Cl for Chlorine: Na-Cl makes the salt you see!
Na┬аCl тАФ Sodium chloride (Common salt)
HCl+NaOHтЖТNa┬аCl+H2тАЛO тАФ Neutralization reaction
Sodium chloride is formed through the transfer of electrons from a sodium atom to a chlorine atom, creating positively charged sodium ions (Na+) and negatively charged chloride ions (ClтИТ). The strong electrostatic attraction between these oppositely charged ions results in a stable ionic crystal lattice.
It is an ionic compound held together by strong electrostatic forces.
It conducts electricity in aqueous solution or molten state due to free-moving ions.
It has a high melting point of approximately 801┬░C.
Crucial for maintaining fluid balance, nerve conduction, and muscle function in the human body.
High dietary intake can contribute to high blood pressure and related cardiovascular complications.
Food seasoning and preservation.
Raw material for producing chlorine, hydrogen, and sodium hydroxide via the chlor-alkali process.
Option A (KCl) is potassium chloride (often used as a salt substitute).
Option C (Na2тАЛCO3тАЛ) is sodium carbonate (washing soda).
Option D (NaOH) is sodium hydroxide (caustic soda).
B is correct тАФ Common salt has the chemical formula Na┬аCl, which stands for sodium chloride.
Questions involving chemical formulas of common commercial compounds (like washing soda, baking soda, and common salt) frequently appear in RRB CBT-1 examinations, so memorize their formulas and systematic names thoroughly.
