Sodium is a soft wax-reactive metal with the chemical formula Na and belongs to the group of alkali metals. It is found in nature with various compounds, especially salt water and halides. Sodium is a highly reactive element and therefore can never be found freely in nature. This element is very reactive, it oxidizes in air and its powder in water explodes.
Sodium compounds such as NaCl or sodium chloride (NaCl), sodium carbonate (Na2CO3), sodium bicarbonate (CO3NaH), sodium phosphate (Na3PO4), sodium hypochlorite (NaOCl), sodium sulfide (Na2S), sodium Na2SO, Na2SO3. .. It is used for chemical industries, water purification, glass making, metal, paper making, oil and gas industries, soap making, textile, health, soap making, etc.

Caustic soda with the chemical formula of NaOH, odorless solid, clear crystal, non-volatile and highly corrosive. Easily absorbs moisture from the air and when dissolved with water or neutralized with acid; It produces a lot of heat. The most common forms are in the form of liquid , flake , ash and in the form of pearls. The most important features of caustic soda are:

• Fat is very strong
• Neutralizing acidic environments
• PH regulator
Caustic soda due to its many characteristics, in various industries such as water purification, canning, beverage, oil refining, sugar production, paper production, pharmaceuticals, detergents, metals and metal plating industries, polymer industries, materials production It is used in chemical, oil and gas, petrochemical industries, etc.

Calcium is one of the most important elements in the form of white crystals with the chemical formula of Ca. This element is less active than alkali metals and is found in abundance in nature, as calcium compounds make up more than 60% of the Earth's crust. Calcium is the most abundant substance in the human body, especially in the bones and teeth, which is useful for preventing osteoporosis, muscle contraction, heart rate, etc.
The industry produces calcium metal from the electrolysis of calcium chloride and a mixture of potassium chloride and fluoride. Calcium reacts easily with acids and water to produce hydrogen. Calcium nitrate, calcium chloride, calcium sulfate, calcium carbonate, etc. are important compounds containing calcium. Calcium is used in various industries, including agriculture, pharmacy, cement, steel, oil and gas, etc

Acid is a chemical substance whose solutions have a pH less than seven and are corrosive. An acid is actually a positive hydrogen molecule or ion that is able to lose a proton or H + and form a covalent bond with an electron pair. Acids have the ability to react with some metals and all bases (neutralize bases) which cause the detectors to discolor and have a sour taste. Types of acids are named based on their non-metals or anions. Accordingly, the types of acids are:
• Organic acids such as perchloric acid, sulfuric acid, etc.
• Oxygenated mineral acids such as carbonic acid, phosphoric acid, etc.
• Mineral acids without oxygen such as hydrochloric acid and ...
Acids are used to prevent corrosion of metals in automotive battery industries, beverage and food supplements, chemical catalysts and oil and gas industries, especially in the production of gasoline, etc.
