Is cobalt II carbonate a solid?

Cobalt (II) carbonate is an inorganic compound that is also known as cobaltous carbonate. It is a reddish paramagnetic solid whose chemical or molecular formula is CoCO₃.

Is cobalt II hydroxide a 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). ), which incorporates other anions in its molecular structure.

Is cobalt II sulfate a solid?

Cobalt(II) sulfate is a red (anhydrous, monohydrate) or pink (hexa-, heptahydrate) crystalline solid, soluble in water, with the hydrated form more soluble in methanol than the anhydrous one.

Is cobalt solid or liquid?

Cobalt is a lustrous very hard silvery metal belonging to a group called the “transition metals”.

Is cobalt a gas or solid?

solid
Cobalt is a chemical element with symbol Co and atomic number 27. Classified as a transition metal, Cobalt is a solid at room temperature.

What is cobalt 2+ called?

Cobalt(2+) is a divalent metal cation, a cobalt cation and a monoatomic dication.

Is cobalt II stable?

(ii) Cobalt(II) is stable in aqueous solution but in the presence of complexing reagents it is easily oxidised.

Is cobalt sulfate aqueous or solid?

crystalline solid
Description. Cobalt Sulfate is an odorless monoclinic crystalline solid that is soluble in water, liquifying slowly around 100 °C and becoming anhydrous at 250 °C. It is slightly soluble in ethanol and very soluble in methanol.

Is hydroxide solid or liquid?

solid
At room temperature, sodium hydroxide is a white crystalline odorless solid that absorbs moisture from the air. It is a manufactured substance. When dissolved in water or neutralized with acid it liberates substantial heat, which may be sufficient to ignite combustible materials.

Is hydroxide solid liquid or gas?

At room temperature, sodium hydroxide is a white, odorless solid.

Is cobalt III hydroxide a solid?

The brownish-black form is a stable solid and can be prepared by reaction of water solutions of cobalt(II) chloride and sodium hydroxide, followed by oxidation with ozone.

Is cobalt II sulfide aqueous?

About Cobalt(II) Sulfide
Organometallic forms are soluble in organic solutions and sometimes in both aqueous and organic solutions.

Why is cobalt II stable in aqueous solution?

Co(II) is stable in aqueous solutions as water is weak field ligand. But in the presence of strong field ligands, it is oxidized to Co (III).

Is sulfate solid liquid or gas?

Sodium sulfate (also known as sodium sulphate or sulfate of soda) is the inorganic compound with formula Na₂SO₄ as well as several related hydrates. All forms are white solids that are highly soluble in water.

Is cobalt hard or soft?

Cobalt is a shiny, brittle metal that is used to produce strong, corrosion and heat-resistant alloys, permanent magnets and hard metals.

Is cobalt a metal or rock?

metal
Cobalt is a grayish-white metal with the chemical symbol Co. As a pure metal, cobalt is hard and brittle. It makes a strong alloy with other metals, has a high melting point and low conductivity.

Is there cobalt in water?

Small amounts of cobalt are present naturally in rock, soil, water, plants, animals and air.

Is cobalt a hard metal?

Cobalt is a hard, brittle metal that occurs naturally in the environment and is a common by-product of nickel and copper mining activities. Cobalt can enter the environment from burning coal or oil, processing of cobalt-containing ores, and the production and use of cobalt- containing chemicals.

Is cobalt actually blue?

In the art of painting cobalt is mainly known as a colour blue. The pigment that was traditionally extracted from a mineral comes, however, in various shades, varying from yellow to red and from blue to green. It was traditionally used to colour glass and ceramics.
