What is Sodium Chloride CAS 7647-14-5?

Sodium chloride is common salt, supplied as white or colorless crystals, pellets or granular material. Industrial and water-treatment grades are used for ion-exchange regeneration, chlor-alkali production, deicing and many process applications.

Why is Sodium Chloride used in water softening?

It provides sodium ions to regenerate cation-exchange resin. Concentrated brine displaces hardness ions such as calcium and magnesium from the resin, restoring its softening capacity and helping prevent scale in boilers, pipes and equipment.

What form of salt is best for water softeners?

High-purity compressed pellets or tablets made from vacuum salt are commonly preferred because they dissolve cleanly, produce little insoluble residue and are convenient to load. Granular or rock salt can also be used where equipment and brine-tank design allow it.

What are the main industrial applications of Sodium Chloride CAS 7647-14-5?

Beyond water softening, industrial salt is used in chlor-alkali production, deicing and dust control, textile dyeing, leather processing, oil and gas drilling fluids and other chemical manufacturing processes. Food or pharmaceutical use requires the appropriate food/pharma grade.

Which purity and impurities matter for water-treatment salt?

Check NaCl purity, moisture, water-insoluble matter, calcium, magnesium and sulfate. High-purity water-softening salt with low calcium, magnesium and sulfate reduces brine-tank residue, resin fouling and maintenance frequency.

How soluble is Sodium Chloride and does it cake?

Sodium chloride dissolves readily in water, especially in pellet, tablet or fine granular form. It is hygroscopic and can cake in humid conditions, so it should be kept in closed packaging or covered bulk storage before use.

Product Description

Sodium Chloride, CAS 7647-14-5, also known as common salt or halite, is the ionic compound NaCl; the EC/EINECS number is 231-598-3.

Synonyms: common salt; natrium chloride; halite; rock salt; hydrochloric acid sodium salt.

CAS: 7647-14-5.

Molecular formula: NaCl.

Molecular weight: 58.44 g/mol.

EC number: 231-598-3.

It is supplied as white or colorless crystals, compressed pellets, tablets or granular material.

Water-softening salt is typically at least 99.5% NaCl with low moisture, water-insoluble matter, calcium, magnesium and sulfate.

It dissolves readily in water, especially in pellet, tablet or fine granular form.

It provides sodium ions to regenerate cation-exchange resin, displacing calcium and magnesium hardness ions.

It is used in residential, commercial and industrial water softeners, boiler feed-water treatment and RO pre-treatment.

It is used in chlor-alkali production, salt chlorination for pools, textile dyeing and leather processing.

It is used for deicing, dust control, oil and gas drilling fluids and other chemical processes.

Confirm NaCl purity, moisture, water-insoluble matter, calcium, magnesium, sulfate, whiteness and pellet or particle size.

Keep bags tightly sealed in a cool, dry, ventilated area, as sodium chloride is hygroscopic and can cake in humid conditions.

Store away from incompatible materials and do not stack too high to avoid crushing pellets.

Confirm packaging with the requested quantity and destination requirements.
