Is Cobalt Chloride Nonpolar?

a) Cobalt(II) chloride must be polar, as it dissolves in polar water.

Is cobalt chloride colorless?

Anhydrous cobalt chloride, CoCl₂, is blue in colour. As it absorbs water, it turns pink.

Is cobalt chloride solid or aqueous?

The anhydrous form is a blue crystalline solid; the dihydrate is purple and the hexahydrate is pink. Commercial samples are usually the hexahydrate, which is one of the most commonly used cobalt compounds in the lab.

Is cobalt chloride covalent?

Answer and Explanation: Cobalt(II) chloride is an ionic compound that is highly soluble in water.

Is cobalt chloride flammable?

ICSC 0783 – COBALT (II) CHLORIDE. Not combustible. Gives off irritating or toxic fumes (or gases) in a fire. In case of fire in the surroundings, use appropriate extinguishing media.

What uses 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.

Is cobalt chloride reactive?

COBALT CHLORIDE acts as a weakly acidic inorganic salt, which is soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH’s of less than 7.0. They react as acids to neutralize bases.

Is cobalt hydroxide solid?

) is a pink solid insoluble in water. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa).

Is cobalt carbonate aqueous?

This reddish paramagnetic solid is an intermediate in the hydrometallurgical purification of cobalt from its ores. It is an inorganic pigment, and a precursor to catalysts.
Cobalt(II) carbonate.

Is cobalt bromide aqueous?

Cobalt(II) bromide (CoBr₂) is an inorganic compound. In its anhydrous form, it is a green solid that is soluble in water, used primarily as a catalyst in some processes.
Cobalt(II) bromide.

Is cobalt a metal or nonmetal?

metal
Cobalt is a lustrous very hard silvery metal belonging to a group called the “transition metals“. It is one of only 3 ferromagnetic transition elements along with iron and nickel.

Is cobalt chloride soluble?

Cobalt[II] chloride hexahydrate: soluble in water, alcohols, acetone, ether, glycerol. Cobalt[II] oxide: Insoluble in water, soluble in acids or alkalis. Cobalt[II] sulfate: monohydrate: dissolves slowly in boiling water; heptahydrate, soluble in water, slightly soluble in ethanol.

Is cobalt chloride a precipitate?

Cobalt(II) Chloride with Sodium Hydroxide
The result is a red solution and a blue-green precipitate.

Is cobalt fire resistant?

FIRE HAZARDS
* Cobalt is not combustible when in solid or bulk form. However, finely divided Cobalt is FLAMMABLE and will ignite spontaneously in air.

Is cobalt a pyrophoric?

Only certain forms of cobalt metal are pyrophoric.Pyrophoric cobalt is a black powder that burns brilliantly when in contact with oxygen or air.

Is cesium chloride flammable?

Non-combustible. Thermal decomposition can lead to release of irritating gases and vapors. Keep product and empty container away from heat and sources of ignition.

Is cobalt chloride poison a?

A suspected carcinogen and very toxic. Cobalt chloride attacks the blood, liver, thyroid, lungs and connective tissues. It is an eye and respiratory tract irritant and a skin sensitiser.

Is cobalt chloride magnetic?

Cobalt(II) choride hexahydrate,CoCl₂·6H₂O, eventually swings toward a magnet.

What technology is cobalt used in?

Cobalt is an essential metal for the process of magnetic recording technology as used in data recording devices such as hard disk drives or magnetic tape.

Does cobalt react with air?

Cobalt is somewhat of a reactive element. It combines with oxygen in the air, but does not catch on fire and burn unless it is in powder form. Cobalt has the ability to react with most acids to produce hydrogen gas.

Is cobalt chloride an anion?

The chemical formula of the compound is: CoCl2 C o C l 2 . The roman numeral (II) indicates that the cobalt cation has an overall positive charge of +2. The chloride ion is an anion that bears a net negative charge of 1. To have an electrically neutral ionic compound, there must be two chloride ions per cobalt ion.
