Making HClO3

Hello.

I was thinking if could i do some HClO3 with Cl2 as source, puting some Cl2 in water will do HClO3, and puting it in h202 will do hclo4, will this combination really work?

 

or it will do just hcl?

[ce]Cl2[/ce] with [ce]H2O[/ce] will give you [ce]HCl + HOCl[/ce] and [ce]HOCl[/ce] will decompose into [ce]HCl[/ce] and atomic oxygen.

 

They two ways I know of making [ce]HClO3[/ce] are:

 

[ce]Cl2O5 + H2O -> 2HClO3[/ce]

 

[ce]Ba(ClO3)2 + H2SO4 -> BaSO4 + 2HClO3[/ce]

there are some Blatant errors here, according to My source:

 

 

Chlorine has the following oxides:

Cl2O --> anhydride of HOCl

ClO2 --> Mixed anhydride of HClO2 and HClO3

Cl2O6 --> Mixed anhydride of HClO3 and HClO4

Cl2O7 --> anhydride of HClO4

 

So, for HClO3 and HClO2 there is no true anhydride.

 

The route of Ba(ClO3)2 and H2SO4 indeed is suitable for making HClO3.

Finally, HClO3 only exists in solution. Any attempt to isolate HClO3 by taking away the water results in decomposition.

Textbooks are sometimes wrong. Do you have any evidence for the existence of Cl2O5?

 

There are some other oxides of chlorine and they are not generally easy to work with so it can be hard to tell if you have a new compound or just an impure mixture of the other oxides.
