A hydrated salt has a number of waters of hydration combined to each molecule of salt whereas an anhydrous salt is one that has had its waters of hydration removed. An example of a hydrated salt is nickel sulfate hexahydrate, NiSO4·6H2O. The waters of hydration can be removed by a simple heating, resulting in NiSO4(s) + 6H2O(g).
anhydrous means if a substance contains NO water it is anhydrous. but if it is hydrated it contains water.
Hydrated substances are formed by water absorption in the anhydrous substance.
Only some salts have hydrates, not all. These salts contain in the formula water of crystallization.

Anhydrous AlCl3 refers to aluminum chloride that is free from water molecules. It is a dry, solid compound that is commonly used as a catalyst in chemical reactions. Its anhydrous form is important in certain reactions where the presence of water can interfere with the desired outcome.
Anhydrous salts prepared by evaporating the water contained in a hydrated salt. However, anhydrous salts are non-electrolytes, meaning they can't pass an electric current.
When an anhydrous salt retain water in the crystalline structure.
On heating, hydrated salts lose their water of crystallization and as a result, the crystals lose their shape and colour and change to a powdery substance.
Depends on if it is hydrated or not. If hydrated, magnesium sulfate heptahydrate, then (7.6g)/(246.47g/mole)=.0308mole. If anhydrous (7.6g)/(120.415g/mole)=0.063mole.
Anhydrous salts are hard to store because they readily absorb water from the atmosphere, forming hydrated salts. This can change their properties, such as solubility and reactivity, making them less predictable in reactions. Proper storage in airtight containers with desiccants is necessary to prevent moisture absorption.
The hydrated forms of these compounds are lower energy thermodynamically than the anhydrous forms. It takes heat energy to drive the water out of these salts to make them anhydrous. If left in the open, the anhydrous forms will take up water from the atmosphere and re-hydrate themselves. This process releases heat energy, so it "runs downhill" energy-wise.
anhydrous means if a substance contains NO water it is anhydrous. but if it is hydrated it contains water.
In the body salts are dissolved in water, blood etc.
Hydrated substances are formed by water absorption in the anhydrous substance.
The color of an anhydrous compound is sometimes different from the hydrated compound.
Anhydrous sodium carbonate can be converted to hydrated sodium carbonate by simply adding water. When anhydrous sodium carbonate reacts with water, it forms hydrated sodium carbonate through a hydration reaction where water molecules are incorporated into the crystal structure, resulting in a hydrated form of the compound.
cobalt chlorideCompound that exists in two forms: the hydrated salt (CoCl2.6H2O), which is pink, and the anhydrous salt, which is blue. The anhydrous form is used as an indicator because it turns pink if water is present. When the hydrated salt is gently heated the blue anhydrous salt is reformedcobalt chlorideCompound that exists in two forms: the hydrated salt (CoCl2.6H2O), which is pink, and the anhydrous salt, which is blue. The anhydrous form is used as an indicator because it turns pink if water is present. When the hydrated salt is gently heated the blue anhydrous salt is reformedCobalt chloride in simple terms.When the cobalt chloride has no water (ANHYDROUS) it is BLUE. when water is present then the anhydrous cobalt chloride becomes HYDRATED cobalt chloride and it is PINK.
