Rock salt is pulverized. In this process, rock salt is crushed into smaller pieces of rock salt, that still have the same chemical identity. Therefore this is a physical change as there is a change in the form ( smaller pieces) but the chemical identity is the same.

Chemical weathering and erosion occurs when rock is changed into smaller pieces by chemical reactions. Resulting rock is not the same as the original. For example, if acid is poured on chalk (CaCO3) it will fizz. Gases (CO2) are given off and the remaining rock piece is calcium (CaO). The chalk composition changes due to the chemical reaction. The rock had changed to a different chemical composition. The

Rock salt is also used as a source of sodium and chlorine in the chemical industry to melt ice on roads, as part of the process of softening water, and as a seasoning. Under certain conditions, the mineral sylvite (KCl) accumulates in evaporite beds, and this rock is called potash.

Rock Salt is a chemical sedimentary rock that forms from the evaporation of ocean or saline lake waters. It is also known by the mineral name halite. It is rarely found at Earth's surface, except in areas of very arid climate. It is often mined for use in the chemical industry or for use as a winter highway treatment.

Mar 14, 2018When salt is added to the ice bath (usually rock salt in ice cream making), it comes into contact with the thin layer of water on the surface of the melting ice. The salt dissolves and the water becomes salty. This salt water has a lower freezing point, so the temperature of the ice bath can get even colder, thus freezing the ice cream more quickly.

These changes depend on the rock material being weathered, climatic condition and the topographic character of the area. In cold and dry climates and for chemically resistant rocks physical weathering is most important. In hot and humid climates and for rocks that are liable to chemical change, chemical weathering becomes more important.

Salt can vary in colour depending upon its level of purity. There are two main sources of salt. It is harvested directly either from sea water or natural brine, or from rock salt deposits formed by the evaporation of earlier seas that left a layer of rock salt, otherwise known as halite.

- Chemical Sedimentary Rocks. Chemical sedimentary rocks form when crystals precipitate out from a liquid. The mineral halite, also called rock salt, forms this way. You can make halite! Leave a shallow dish of salt water out in the Sun. As the water evaporates, salt crystals form in the dish. There are other chemical sedimentary rocks, like gypsum.

When solution mines are located near chemical plants, they are called brine wells, and the salt is used for chemical production. After the salt is removed from a salt mine, the empty room often stores other substances, like natural gas or industrial wastes. Salt is harvested through solar evaporation from seawater or salt lakes. Wind and the sun evaporate the water from shallow pools, leaving the salt

Chemical reactions can be classified as endothermic (energy is taken in) or exothermic (energy is released). When salt is dissolved it is an endothermic reaction, energy is absorbed to break the bonds, this energy is it heat of solution ( in other words it takes a certain amount of energy to transform solid salt to liquid salt).

In rock salt mining, salt is mined from large underground deposits called beds or domes. It is crushed into manageable chunks and hauled to the surface, where it is screened, bagged, and shipped for further processing into commercial products and food-grade salt.
