The color of ferric nitrate solution?

Submitted by admin on Thu, 12/13/2018 - 07:25

Iron nitrate is  colorless or lavender monoclinic crystal,
True Fe3+ ions and hexahydrate Fe3+ ions are lavender.
However, due to the usual pH conditions, hydrated Fe3+ ions are easily hydrolyzed.

Partially hydrolyzed products such as Fe(OH)2+ and other hydroxylates and oxyhydroxides, OH- and O2- as ligands, their coordination field effect is very strong.

The 3d energy level of Fe3+ is changed to yellow and yellowish brown, which also makes the solution yellow.

Use of zinc chloride

Submitted by admin on Mon, 12/10/2018 - 09:43

Zinc chloride is one of the important products in the inorganic salt industry, and its application range is extremely wide. Zinc chloride is easily soluble in water and is the most soluble in solid salts (25 ° C, 432 g / 100 g) due to its solubility in water to form the acid H [ZnCl 2 (OH)]. Soluble in methanol, ethanol, glycerin, acetone, ether, insoluble in liquid ammonia. It is highly deliquescent and can absorb moisture from the air and deliquesce.

Need to pay attention of Niobium(V) oxide

Submitted by admin on Mon, 12/10/2018 - 09:28

Niobium (V) oxide is used as a single crystal of nickel ruthenate, special optical glass, high frequency and low frequency capacitors and piezoelectric ceramic components. It is also used in the production of various niobium alloys for niobium and special steels. It is a raw material for the preparation of hydrazine and its compounds. Also used as a catalyst, refractory material.

How about kaolin?

Submitted by News on Mon, 12/10/2018 - 07:37

kaolin is a clay mineral, part of the group of industrial minerals, with the chemical composition Al2Si2O5(OH)4. It is a layered silicate mineral, with one tetrahedral sheet of silica (SiO4) linked through oxygen atoms to one octahedral sheet of alumina (AlO6) octahedra.Rocks that are rich in Kaoline are known as kaolin or china clay.

Uses of Antimonous oxide

Submitted by News on Mon, 12/10/2018 - 07:31

Antimonous oxide is a actinic admixture of antimony and oxygen. It consistently occurs in hydrated form, Sb2O5·nH2O.[citation needed] It contains antimony in the +5 blaze state.

The hydrated oxide is able by hydrolysis of antimony pentachloride; or by acidification of potassium hexahydroxoantimonate(V). It may aswell be able by blaze of Antimonous oxide with nitric acid.
