📝 Summary
Sodium Chloride, known as table salt, is a crucial ionic compound made of sodium and chloride ions. Its chemical formula is NaCl, consisting of one sodium ion and one chloride ion that bond in a cubic lattice structure. Sodium Chloride has essential functions in the human body, such as maintaining fluid balance, enabling nerve function, and regulating pH balance. Additionally, it plays vital roles in industrial applications like chemical production and food preservation, highlighting its significance in daily life and health.
Sodium Chloride: The Essential Compound
Sodium Chloride, commonly known as table salt, is a crystalline ionic compound essential for various biological and industrial applications. Composed of sodium (Na) and chloride (Cl) ions, it holds significance beyond just seasoning our food. In this article, we will explore its chemical structure, properties, functions, and various applications.
Chemical Structure of Sodium Chloride
The chemical formula of Sodium Chloride is NaCl. It represents one sodium ion and one chloride ion, which bond together in a strong ionic bond. The sodium ion has a positive charge (Na+), while the chloride ion has a negative charge (Cl–), resulting in a neutral compound overall.
The structure of Sodium Chloride can be represented as a cubic lattice. Each sodium ion is surrounded by six chloride ions, while each chloride ion is similarly surrounded by six sodium ions, forming a repeating three-dimensional grid. This geometric arrangement results in the characteristic cubic crystals of salt.
