Similarly one may ask, what is the name of cro3?

Chromium trioxide is an inorganic compound withtheformula CrO3. It is the acidic anhydride ofchromicacid, and is sometimes marketed under thesamename.

Similarly, what is chromium IV? Chromium dioxide orchromium(IV)oxide is an inorganic compound with theformula CrO2. Itis a black synthetic magneticsolid.

Keeping this in view, what is the formula for chromium IV oxide?

CrO2

What is the structure of CrO5?

In CrO5 there is one oxygen double bonded tothechromium atom and there are two peroxide linkages(-O-O-). Intheequations 1 and 2, I've taken 'x' as the oxidation stateofChromium. This structure of CrO5 is commonly known asthebutterfly structre.

Which state of chromium is most toxic?

The hexavalent state is a major partofchromium in waters. Hexavalent chromiumeasilypenetrates biological membranes and for high oxidizingpotential,is more toxic than theCr+3form.

What level of chromium is toxic?

The median lethal dose of hexavalent chromiumis50–150 mg/kg. The World Health Organization recommendsamaximum allowable concentration of 0.05 milligrams per litreofchromium(VI) in drinking water. In Europe, the useofhexavalent chromium is regulated by the RestrictionofHazardous Substances Directive.

Is chromium cancerous?

The Department of Health and Human Services (DHHS),theInternational Agency for Research on Cancer (IARC), andtheEPA have determined that chromium(VI) compounds areknownhuman carcinogens. In workers, inhalation ofchromium(VI)has been shown to cause lung cancer.Chromium(VI)also causes lung cancer inanimals.

What are the dangers of chromium?

Human occupational experience clearly indicatesthat,when inhaled, chromium compounds are respiratorytractirritants, resulting in airway irritation, airway obstruction,andlung, nasal, or sinus cancer. Dose, exposure duration, andthespecific compound involved can determine chromium'sadversehealth effects.

What is peroxide linkage?

Peroxides are a group of compounds withthestructure R−O−O−R. The O−O group inaperoxide is called the peroxide group orperoxogroup. In contrast to oxide ions, the oxygen atoms intheperoxide ion have an oxidation stateof−1.
