Sodium chloride is an important matrix for maintaining the capacity of extracellular fluid, and also has a certain regulatory effect on the acid-base balance of body fluids. It is also one of the important factors in maintaining neuromuscular stress.
Sodium chloride is an important regulator of electrolyte balance in body fluids. The average amount of total sodium in the normal human body is 150g, of which 44% is present in the extracellular fluid in the form of sodium chloride and about 9% is present in the cell. The constant osmotic pressure in the body is necessary to maintain life, and sodium ions in the extracellular fluid account for 90% of the cation content. Therefore, sodium is an important component in maintaining osmotic pressure and capacity of extracellular fluid. The concentration of sodium chloride in the blood is often maintained at the level of 0.6%, which is necessary to maintain cell excitability and neuromuscular stress. If a large amount of sodium is lost in the body, it can cause hyponatremia syndrome.

Sodium chloride (NaCl) is an ionic compound composed of positively charged sodium ions (Na⁺) and negatively charged chloride ions (Cl⁻). It's most commonly known as table salt.
In its pure form, it appears as colorless, cubic crystals. It is highly soluble in water and is essential for life. It occurs naturally in large quantities in seawater (as the main mineral constituent) and in underground mineral deposits (rock salt or halite).
Seasoning & Flavor Enhancer: The most familiar use, enhancing the taste of food.
Preservative: Inhibits the growth of bacteria, molds, and yeasts, used in curing meats (bacon, ham), pickling, and preserving fish.
Food Processing Agent: Essential in baking (controls yeast fermentation, strengthens gluten), cheese-making, and butter production.
Essential Nutrient: Crucial for nerve impulse transmission, muscle contraction, and maintaining fluid balance and blood pressure in the body.
Intravenous Saline Solution: A sterile 0.9% sodium chloride solution ("normal saline") is used to rehydrate patients, deliver medications, and maintain fluid volume during surgery.
Wound Cleaning: Saline solution is a gentle, effective way to clean wounds.
Mucolytic & Nasal Rinse: Helps break up mucus and relieve nasal congestion.
Chemical Feedstock: The primary source for the production of chlorine gas (Cl₂) and sodium hydroxide (NaOH) via electrolysis. These are foundational chemicals for:
Plastics (e.g., PVC)
Bleach and disinfectants
Paper pulp processing
Soaps and detergents
De-icing & Anti-icing: Spread on roads and sidewalks in winter to lower the freezing point of water, melting ice and snow.
Water Softening: Used in ion-exchange water softeners to remove calcium and magnesium ions that cause "hard water."
Industrial Dyes & Textiles: Used in the manufacturing and fixing of dyes.
Cleaning Agent: Used as a gentle abrasive for scrubbing (mixed with vinegar or water).
Water Conditioning: Added to home water softener systems.
Animal Husbandry: Provided as a salt lick for livestock to ensure they receive essential sodium and chloride.
Currency & Trade: So valuable in ancient times that it was used as currency (the origin of the word "salary").
Preservation: Before refrigeration, salting was a primary method for preserving food for long journeys and seasons.
Dietary Intake: While essential, excessive consumption is linked to high blood pressure (hypertension) and cardiovascular disease. Moderation is key.
Different Grades: The salt you eat is highly purified. Industrial salt (e.g., for de-icing) is not purified for consumption.
Environmental Impact: Runoff from road salt can damage vegetation, corrode vehicles and infrastructure, and harm freshwater ecosystems.
In summary, sodium chloride is far more than just a table seasoning. It is a biological necessity, a cornerstone of the chemical industry, and a multi-purpose material with applications ranging from life-saving medicine to manufacturing and winter safety.
