Question

Carnallite is $KCl.MgC{l_2}.6{H_2}O$

Answer 1

Hint: We have to remember that the carnallite is an evaporite mineral, a hydrated potassium magnesium chloride with equation \[KMgC{l_3}6({H_2}O)\] ). It is dynamically shaded yellow to white, ruddy, and some of the time boring or blue.

Complete step by step solution:
Now we can discuss about the nature and properties of carnallite as,
Carnallite is an evaporite mineral, a hydrated potassium magnesium chloride with formula $KCl.MgC{l_2}.6{H_2}O$.
It is fluidly shaded yellow to white, ruddy, and in some cases dull or blue. It is generally huge to sinewy with uncommon pseudohexagonal orthorhombic gems.
The mineral is deliquescent (retains dampness from the encompassing air) and examples must be put away in an impenetrable container.
Carnallite is an unprecedented twofold chloride mineral that lone structures under explicit natural conditions in a dissipating ocean or sedimentary bowl.
It is dug for both potassium and magnesium and happens in the evaporite deposits.
Carnallite has corner-and face-sharing.
Face sharing makes more possibility of unsteadiness, as indicated by the third of Pauling's rules.
In carnallite, the water particles encase the magnesium particles. This keeps the magnesium and the chloride from collaborating legitimately; all things considered, the water atoms go about as charge transmitters.
 The five chloride anions are each organized to two potassium cations just as four water molecules.

Note: Now we can see the uses of carnallite in various fields as,
Carnallite is generally utilized in manures. It is a significant wellspring of potash.
Only sylvite outclasses carnallite's significance in potash production.
 Both are remarkable in light of the fact that they are a portion of the last evaporates to form.
 Soluble potassium salts are the principle hotspots for manure. This is on the grounds that the potassium is hard to isolate from insoluble potassium feldspar.
Carnallite is a minor wellspring of magnesium around the world; in any case, it is Russia's primary source.
