How do you make cobalt chloride hexahydrate?

The method comprises the following steps of: reacting a metal cobalt slice with a concentrated nitric acid so as to generate a cobalt nitrate, directly reducing the cobalt nitrate by using formaldehyde in the condition of the esistence of hydrochloric acid so as to remove the nitrate radical to generate a cobalt

What is the correct name for CoCl2 times 6H2O?

Cobalt (II) chloride hexahydrate
Hence the name of the compound CoCl2. 6H2O is Cobalt (II) chloride hexahydrate. The term ‘hexa’ is used since it contains 6 water molecules.

What is the formula for cobalt hexahydrate?

Cobalt Hexahydrate

What is hexahydrate?

hexahydrate (plural hexahydrates) (chemistry) A hydrate whose solid contains six molecules of water of crystallization per molecule, or per unit cell.

Is CoCl2 6H2O solid?

Synonyms: Cobaltous chloride hexahydrate; Cobalt muriate hexahydrate. Appearance: purple solid.

Why does Al Form hexahydrate?

Anhydrous aluminium chloride is hygroscopic, having a very pronounced affinity for water. It fumes in moist air and hisses when mixed with liquid water as the Cl⁻ ligands are displaced with H₂O molecules to form the hexahydrate [Al(H ₂O) ₆]Cl ₃.

What is the cobalt chloride?

Commercially, cobalt (II) chloride is often used to make sealants, adhesives, and glues. It is also used for electroplating, particularly for plating objects with cobalt metal. Surface treating metal is another common industrial use of the compound.

Does cobalt chloride hexahydrate dissolve in water?

This product is soluble in water (100 mg/ml), yielding a clear, red solution.

What color is cobalt chloride hexahydrate?

Cobalt(II) chloride hexahydrate is the most common form of this inorganic compound which is a deep rose color in the hydrated form. The dramatic color change of blue-purple Cobalt(II) chloride (sc-252623) to the rose color when hydrated makes Cobalt(II) chloride an excellent indicator for water in dessicants.

What is chromium chloride hexahydrate used for?

The most common form of the trichloride is the dark green hexahydrate, CrCl₃ · 6 H₂O. Chromium chlorides find use as catalysts and as precursors to dyes for wool.

Why is cobalt chloride hexahydrate pink?

Cobalt chloride, CoCl₂, is an inorganic compound that changes color from blue to pink in response to humidity. As humidity increases, cobalt chloride gradually changes color from blue, to pink, to a lighter pink, almost white.

What happens when water is added to CoCl2 6h2o?

Cobalt chloride hexahydrate is pink in color and cobalt chloride is blue in color. When the reaction is reversed by adding water, the blue solution of cobalt chloride changes to pink color and heat is evolved, therefore the reaction is exothermic.

What are the colors of CoCl2 and CoCl2 * 6H2O?

There are of course many colorful chemicals.

How many atoms are in CoCl2 ∙ 6H2O?

CoCl2 ·6H2O
The compound with the water removed is known as anhydrous. The molar mass of CoCl2 is 129.83 g/mol The molar mass of H2O is 18.02 g/mol and the molar mass of 6H2O is (6)( 18.02 g/mol) = 108.12 g/mol The molar mass of CoCl2∙6H2O is 237.95 g/mol (The 6 in front of the H2O needs to be taken into account!)

Does CoCl2 exist?

It is a manufactured chemical, but small amounts occur naturally from the break down of chlorinated compounds. Phosgene is used in the manufacture of other chemicals such as dyestuffs, isocyanates, polycarbonates and acid chlorides; it is also used in the manufacture of pesticides and pharmaceuticals.

What is the common name of cobalt chloride?
