Oxidation state
In chemistry, the oxidation state is an indicator of the degree of oxidation of an atom in a chemical compound. The formal oxidation state is the hypothetical charge that an atom would have if all bonds to atoms of different elements were 100% ionic. Oxidation states are typically represented by...

- 2 ClO2 → ClOClO3
Chlorine perchlorate can also be made the following reactions at -45°C.
- CsClO4 + ClOSO2F → Cs(SO3)F + ClOClO3
Chlorine perchlorate is a pale greenish liquid which decomposes at room temperature.
Properties
It is less stable than ClO2 and decomposes to O2, Cl2 and Cl2O6 at room temperature.- 2 ClOClO3 → O2OxygenOxygen is the element with atomic number 8 and represented by the symbol O. Its name derives from the Greek roots ὀξύς and -γενής , because at the time of naming, it was mistakenly thought that all acids required oxygen in their composition...
