Why does halite dissolve in water?
Halite dissolves in water because the attraction between the water molecules (polarity) is strong enough to break the ionic bonds holding the sodium and chloride ions together in the halite crystal structure. As water molecules surround the individual ions, they effectively pull them away from the crystal and into solution.
Do halite crystals form when fresh water evaporates?
Halite is rock salt. Even some fresh water lakes have Na+ and Cl- dissolved in them, so I would guess that yes, some halite forms. But probably not all that much compared to a salt lake evaporating.
How do you calcite from halite?
To separate calcite from halite, you would typically use a method based on their differing solubilities in water. Halite (sodium chloride) dissolves easily in water, while calcite (calcium carbonate) is much less soluble. By adding water to a mixture of the two, halite will dissolve, and calcite will remain as a solid. The solution can then be filtered to remove the dissolved halite, leaving behind the calcite.
Is halite in rocks dissolving in water mechanical or chemical?
Halite dissolving in water is a chemical process. When halite (sodium chloride) comes into contact with water, it dissociates into its constituent ions (sodium and chloride) through a chemical reaction. This process alters the chemical composition of the halite, distinguishing it from mechanical processes, which do not change the chemical structure of materials.
What happens when a jar of water with dust and dirt is stirred is left undisturbed for a few hours or days?
When a jar of water with dust and dirt has been stirred and then left undisturbed for a few days, the dust and dirt will settle to the bottom of the jar. Leaving in an undisturbed state will cause the water to separate from the heavy debris that settles on the bottom of the jar.
What happens when a teaspoon of table salt is stirred into a glass of water?
It dissolves.
What happens when sugar and glycerin together stirred in water?
it becomes a soap
When halite dissolves in water what happens to the chlorine?
Dissolving sodium chloride in water, chlorine become a cation: NaCl---------Na+ + Cl-
What happens to water molecules when they are stirred?
When water molecules are stirred, they gain kinetic energy and move more rapidly. As a result, they collide and interact more frequently with each other, leading to the dispersion of any solutes in the water and a more homogeneous mixture.
What happens when sugar and glycerin are put into water and stirred?
When sugar and glycerin are put into water and stirred, they will dissolve and form a homogeneous mixture. The sugar molecules will break down and disperse in the water, while the glycerin will dissolve and mix evenly with the water, creating a sweet and viscous solution.
Does halite come from the cooling of lava?
No. Halite forms when various bodies of water evaporate. Halite is the mineral name for salt.
Why is water stirred when added to a mixture?
To smoothly mix up the ingredients. water is stirred into the mix.

What are the ingredients in mineral water?
halite is one mineral in mineral water. Halite is used as table salt. It forms when water evaporates and leaves behind the salt.

How can tell when minerals is calcite or halite?
Halite will be easily soluble in water, calcite won't. Calcite has excellent rhombohedral cleavage, halite has excellent cubic cleavage. Halite will taste salty, calcite won't.
