Does halite have a crystal structure?
Halite (salt) – is naturally formed, is solid, does have a definite chemical composition that can be expressed by the formula NaCl, and does have a definite crystalline structure. Thus halite is a mineral.
How did halite grow and develop a crystal structure?
Underground Halite deposits are often mined by drilling wells into the salt layer, and bringing in hot water which quickly dissolves the salt into a brine. The brine is saturated with dissolved salt and is then pumped out. Hopper-shaped cubes may result as the brine evaporates and the crystal grows.
What is the crystal form habit of table salt?
Sodium chloride crystals are cubic in form. Table salt consists of tiny cubes tightly bound together through ionic bonding of the sodium and chloride ions. The salt crystal is often used as an example of crystalline structure.

How do halite crystals form?
Halite is mainly a sedimentary mineral that usually forms in arid climates where ocean water evaporates. Over geologic time, several enormous salt deposits have been formed when repeated episodes of seawater evaporation occurred in restricted basins.
What is the halite of hardness?
2-2.5
Halite has a hardness of 2-2.5, therefor it is only harder than talc on Mohs’ scale.
What is the halite table salt of chemical composition?
Halite, commonly known as table salt or rock salt, is composed of sodium chloride (NaCl).
