Sol:
Sol je mineral koji se prvenstveno sastoji od natrijevog klorida (NaCl), kemijskog spoja koji pripada većoj klasi soli; sol u obliku prirodnog kristalnog minerala poznata je kao kamena sol ili halit. Sol je prisutna u velikim količinama u morskoj vodi. Ocean sadržava oko 35 g (1,2 oz) krutih tvari po litri morske vode, saliniteta od 3,5%.
Kamena sol:
To je vrsta soli, mineralni (prirodni) oblik natrijeva klorida (NaCl). Halit tvori izometrične kristale. Mineral je obično bezbojan ili bijel, ali također može biti svijetloplav, tamnoplav, ljubičast, ružičast, crven, narančast, žut ili siv ovisno o uključivanju drugih materijala, nečistoća i strukturnih ili izotopskih abnormalnosti u kristalima. Obično se javlja s drugim mineralima evaporita kao što su neki od sulfata, halogenida i borata. Halit se uglavnom pojavljuje unutar sedimentnih stijena gdje je nastao isparavanjem morske ili slane jezerske vode tijekom velikog vremenskog perioda.
Morska sol:
To je sol koja nastaje isparavanjem morske vode. Koristi se kao začin jelima, kuhanju, kozmetici i za konzerviranje hrane. Također se naziva lovorova sol, solarna sol ili jednostavno sol. Poput vađene kamene soli, proizvodnja morske soli datira još iz prapovijesti. Iako je glavna komponenta natrijev klorid, preostali dio može biti u rasponu od manje od 0,2 do 10% drugih soli. To su uglavnom kalcijeve, kalijeve i magnezijeve soli klorida i sulfata uz znatno manje količine mnogih elemenata u tragovima koji se nalaze u prirodnoj morskoj vodi. Iako sastav komercijalno dostupne soli može varirati, ionski sastav prirodne slane vode je relativno konstantan.
Zadatci za logiranje:
1. Koja vrsta soli se može dobiti isparavanjem morske vode?

Salt:
Salt is a mineral consisting primarily of sodium chloride (NaCl), a chemical compound that belongs to the larger class of salts; salt in the form of a natural crystalline mineral is known as rock salt or halite. Salt is present in large quantities in seawater. The ocean contains about 35 g (1.2 oz) of solids per liter of seawater, with a salinity of 3.5%.
Rock salt:
It is a type of salt, the mineral (natural) form of sodium chloride (NaCl). Halite forms isometric crystals. The mineral is usually colorless or white, but can also be light blue, dark blue, purple, pink, red, orange, yellow, or gray depending on the inclusion of other materials, impurities, and structural or isotopic abnormalities in the crystals. It usually occurs with other evaporite minerals such as some of the sulfates, halides, and borates. Halite mainly occurs within sedimentary rocks where it was formed by the evaporation of sea or salt lake water over a long period of time.
Sea salt:
It is a salt that is formed by the evaporation of sea water. It is used as a seasoning for dishes, cooking, cosmetics and food preservation. It is also called bay salt, solar salt or simply salt. Like mined rock salt, the production of sea salt dates back to prehistoric times. Although the major component is sodium chloride, the remainder may range from less than 0.2 to 10% of other salts. These are mainly calcium, potassium and magnesium salts of chlorides and sulfates with much smaller amounts of many trace elements found in natural seawater. Although the composition of commercially available salt can vary, the ionic composition of natural salt water is relatively constant.
Logging tasks:
1. What type of salt can be obtained by evaporating seawater?
2. Why is salt white?
3. What color is the salt from the Ston salt pan?
4. Attach a photo of you, your GPS or nickname written on paper, palm, T-shirt, etc. with your application.
