rubidium dichromate formula

The simplest binary ionic compound formed from each ion or element pair is called an empirical formula. Ionic compounds are characterized by their positive and negative charges exactly canceling each other. Compounds of opposite cations and anions are not considered to be ionic compounds; they are covalent compounds.

Common ionic compounds are sodium chloride, potassium chloride, and calcium chloride. These compounds are used as salts to melt ice on roads and sidewalks in winter.

Chromium is commonly found in water as the polyatomic ions chromate (CrO4 2 ) and dichromate (Cr2O7 2 ). The chromate anion is intensely colored, while the dichromate anion is yellow-orange at basic pH values.

Chromate has a strong oxidizing activity. It is a significant biomolecule and can enter the cell through sulfate and phosphate transporters.

It is a major component of secondary frequency references in radio transmitters and receivers. It is also used in the development of lasers and other electro-optic devices.

Various crystalline and amorphous forms of chromium are commercially available. These include chromate, nitrate, alum, and picolinate.

Rubidium is used as a component of atomic clocks and as a radioactive source. It is an important chemical in telecommunications and atomic energy.

The electronic spectra of chromium-containing biomolecules are usually quite simple, giving little information about chromium’s coordination and interactions. However, ESR spectroscopy can reveal some features of Cr3 + complexes that are useful for characterizing the chemistry and biochemistry of chromium.
