Making HClO3

[Mr.Chockuls]

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?

[YT2095]

no, not really, Why do you want this acid anyway?

[thedarkshade]

Cl wouldn't work I think but you could find [ce]Cl2O5[/ce] useful. Just to dissolve it in water

 

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

[Mr.Chockuls]

i want it because i was meaning if someone can make any chlorate easly. i see now' that is better doing with salt, anyway.

thanks guys, i have a source of ClO2 but not of Cl2O5, thanks.

Thanks For You Chockuls

You Mean

Hclo3 +h2o2___________hclo4

My eyes hurt...

 

Learn how to type proper molecular formulas, buy a book, rid yourself of the idea that only explosions are fun, then we'll talk again.

[YT2095]

lol, it gets worse, this

Hclo3 +h2o2___________hclo4

 

wouldn`t even work anyway!

[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]

Very likely it wont work.

[YT2095]

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.

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

I just checked my chemistry book an it is as it follows:

 

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

 

[ce]Cl2O7 + H2O -> 2HClO4[/ce]

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.
