Chromium II acetate, also known as chromium acetate, is a chemical compound with the formula Cr(O2CCH3)2. It is a pale green or yellowish solid that is soluble in water and many organic solvents. Chromium II acetate is commonly used in the production of pigments, dyes, and inks, as well as in the tanning of leather.
Chromium II acetate is produced by the reaction of chromium oxide with acetic acid. It can also be synthesized from chromium metal and acetic acid. The resulting product is a pale green or yellowish solid that is highly soluble in water and organic solvents. Chromium II acetate can be converted to other chromium compounds by reacting it with various chemicals.
One of the main uses of chromium II acetate is in the production of pigments and dyes. Chromium compounds have been used for centuries as pigments due to their bright colors and ability to withstand fading. Chromium II acetate is often used to produce yellow, orange, and red pigments, which are used in a variety of applications including paints, inks, and plastics.
In addition to its use in pigments, chromium II acetate is also used in the tanning of leather. Tanning is the process of converting animal hides into leather, which involves treating the hides with chemicals to preserve them and make them more durable. Chromium II acetate is one of the chemicals commonly used in the tanning process due to its ability to fix the hides and prevent them from decomposing.
While chromium II acetate has many useful applications, it can also be hazardous if not handled properly. Chromium compounds can be toxic if inhaled or ingested, and contact with the skin can cause irritation. It is important to take proper precautions when handling chromium II acetate, such as wearing protective clothing and using it in a well-ventilated area.
In conclusion, chromium II acetate is a versatile chemical compound with a variety of uses, including the production of pigments, dyes, and inks, and in the tanning of leather. It is important to handle it safely and take proper precautions when working with it.
Chromium II acetate
Because such self-serving edits are the main contributions from infrequent editors. They are all the same. I put my molfile in the image page, so if you can do better given the data, go for it! CONDITIONS FOR SAFE STORAGE: Store in cool, dry, and well-ventilated area. The same basic structure is adopted by 2 OAc 4 H 2O 2 and 2 OAc 4 H 2O 2, although these species do not have such short M---M contacts. Cr2 OAc 4 H2O 2 is a reddish diamagnetic powder, although diamond-shaped tabular crystals can be grown. In time, the color of the solution is turning bright blue, the color of the hexaaqua monomer of Cr II. The same basic structure is adopted by Rh 2 OAc 4 H 2O 2 and Cu 2 OAc 4 H 2O 2, although these species do not have such short M—M contacts.

Assemble an apparatus as shown in Fig. You do not need to be an expert to help, but you do need access to good reference books. The above information is believed to be correct but does not purport to be all inclusive and shall be used only as a guide. There wasn't one when I got here. Structure The Cr 2 OAc 4 H 2O 2 molecule contains two atoms of chromium, two ligated molecules of water, and four monoanionic acetate ligands.
An Experiment on the Synthesis of Chromium (II) Acetate Hydrate
This quadruple bond is also confirmed by the low magnetic moment and short intermolecular distance between the two atoms of 236. DISPOSAL CONSIDERATIONS Dispose of in according to local, state, and federal regulations. Consistent with the fact that it is non-ionic, Cr2 OAc 4 H2O 2 exhibits poor solubility in water and methanol.

The information in this document is based on the present state of our knowledge and is applicable to the product with regard to appropriate safety precautions. HANDLING AND STORAGE PRECAUTIONS FOR SAFE HANDLING: Wear appropriate personal protective equipment. VENTILATION: Provide local exhaust, preferably mechanical.
Due to its various colorful compounds, Chromium was named after the Greek word 'chroma. I don't understand why my addition was stroke out by Smokefoot, as I merely added a reference to a currently existing text. Because it is so easily prepared, Cr 2 OAc 4 H 2O 2 is often used as a starting material for other, chromium II compounds. Bis acrylonitrile nickel 0 , 2312 l,2-Bis dichlorophosphino ethane, 0797 Bis trimethylsilyl phosphonite, 2611 Bromodimethylborane, 0887 Preparation of Chromium II Acetate. Get medical attention if necessary.
If conscious, wash out mouth with water. STABILITY AND REACTIVITY STABILITY: Stable HAZARDOUS POLYMERIZATION: Will not occur CONDITIONS TO AVOID: Avoid air and moisture INCOMPATIBILITY: Strong oxidizing agents. A recent protonation and The mixture is The chromium II acetate thus obtained can be converted into other chromium II salts by observing the same conditions as those for the above synthesis. Avoid formation of dusts and aerosols. Another thing - I've just noticed an earlier message from you, bearing the title "Congratulations".
Use with adequate ventilation. See reverse side of invoice or packing slip for additional terms and conditions of sale. The equilibria are shown below. Avoid contact with skin and eyes. I am sick of this rotten behavior that does the opposite of what people claim - you clutter up a general article with microscopic, ego-focused details. METHODS AND MATERIALS FOR CONTAINMENT AND CLEANING UP: Sweep up and place in suitable container for proper disposal. Do you agree with adding Beneš et al.
ADDITIONAL PROTECTION: Provide eyewash stations, quick-drench showers and washing facilities accessible to areas of use and handling. SKIN CONTACT: May cause irritation. ENVIRONMENTAL PRECAUTIONS: Prevent spillage from entering drains or allowing to be released into the environment. FIRST AID MEASURES EYE EXPOSURE: Flush eyes with plenty of water. Because it is so easily prepared, Cr 2 OAc 4 H 2O 2 is often used as a starting material for other, chromium II compounds. This formula is commonly abbreviated Cr2 OAc 4 H2O 2.
Because the molecule contains chromium in a +2 oxidation state it is a good reducing agent. Journal of the American Chemical Society. The Synthesis and Characterization of Inorganic Compounds. I hope that you are sincere, in which case I offer you devoted help and sincere advice. EYE PROTECTION: Wear chemical safety glasses or goggles and face shield.
Therefore, you have to dissolve chromous II acetate under anaerobic conditions in oxygen-free water. When I edit, I try to remember that most readers do not care about details from my world. Avoid breathing vapors, mist, gas, or dust. Avoid the formation of dust. The hit rate on these articles is high. Structure The Cr 2 OAc 4 H 2O 2 molecule contains two atoms of 4h symmetry ignoring the position of the hydrogen atoms.
OTHER INFORMATION Safety Data Sheet according to Regulation EC No. This red-coloured compound features a quadruple bond. The quadruple bond between the two chromium atoms arises from the overlap of four d-orbitals on each metal with the same orbitals on the other metal: the z 2 orbitals overlap to give a History 2 OAc 4 H 2O 2. Still, even under oxygen-free conditions, decomposition of the quadruple bond is observed to some extent. DECOMPOSITION PRODUCTS: Chromium oxide and carbon oxides. Air and moisture sensitive.
