How do you calculate the formula of hydrated Barium Chloride given that a sample of 10g of BaCl2.nH2O crystals lost 1.475g of of water on heating?
Mass of BaCl2 = crucible + lid + BaCl2.nH2O - empty crucible + lid
Mass of water contained in hydrated BaCl2: Initial mass - final mass
No. of moles of H2O in hydrated salt = No. of moles = mass of H2O/formula mass of H2O Use this answer in ratio
No. of moles of BaCl2 in 3.399 g = No. of moles = mass of BaCl2/formula mass of BaCl2 Use this answer in ratio
The ratio of BaCl2 to H2O is 1 : 2

What colour is hydrated copper chloride in water?
Hydrated copper chloride in water is typically blue in color.
What color is hydrated copper chloride in water?
Hydrated copper chloride in water appears blue-green due to the presence of copper ions in solution.
What color is associated with the hydrated form of cobalt chloride?
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.
When salt crystals are placed in water the sodium and chloride ions cannot reform salt crystals why?
When salt crystals are placed in water, the sodium and chloride ions dissociate from each other due to the polar nature of water molecules. The water molecules surround the individual ions and prevent them from recombining to form salt crystals. This dissolution of the salt into its constituent ions is due to the strong interaction between the water molecules and the ions.
What does Magnesium chloride and water form?
When magnesium chloride is dissolved in water, it forms a clear liquid solution. This solution contains magnesium ions (Mg2+) and chloride ions (Cl-), which are the products of the dissociation of magnesium chloride in water.
Will damp cobalt chloride turn back blue once dried?
Solid Cobalt chloride crystals are pink when hydrated with water. If you heat the crystal, the water of crystallisation in the crystals will evaporate, leaving you with solid anhydrous cobalt chloride crystals which are blue in colour.
What colour is hydrated copper chloride in water?
Hydrated copper chloride in water is typically blue in color.
Formula for hydrated copper 2 chloride?
The formula for hydrated copper(II) chloride is CuCl2·xH2O, where x represents the number of water molecules attached per copper(II) chloride unit.

What is fecl3.7h2o?
FeCl3.7H2O is the chemical formula for iron(III) chloride heptahydrate, which is a hydrated form of iron(III) chloride containing 7 water molecules per iron ion. It appears as yellow crystals and is commonly used as a catalyst in organic reactions and as a flocculating agent in wastewater treatment.

What is meant by the word anhydrous when applied to a chemical?
Anhydrous simply means 'without water'. The opposite is a hydrated substance, in which salt crystals contain water as an integral part of the crystal. For example, anhydrous cobalt(II) chloride, CoCl2, is a blue powder. Add water and you form cobalt(II) chloride hexahydrate, CoCl2.6H2O, which is a pink colour. Anhydrous cobalt chloride can be used to test for the presence of water because of this dramatic colour change. In addition, hydrated copper(II) sulfate, CuSO4.5H2O, forms bright blue crystals. Heating them drives off the water of crystallisation and anhydrous CuSO4, a grey/white powder, is formed. Adding water will reform a blue solution of the hydrated salt.
Is NaCl a hydrated salt?
Sodium chloride hasn't hydrates but it is hygroscopic.
What is the correct name of the compound CaCl26H2O?
It is calcium chloride .But it exists as CaCl2.2H2O in its hydrated state.
