HCl + H2O2 = ?

Out of curiosity i once mixed HCl with excess H2O2, and formed an orange solution.

I know this may be a stupid question to ask, but noone i have asked can tell me what this solution is.

Can anyone help? Thnx in advance.

Its not the HCl, more likely a metal salt dissolved in it. Oxidation of ferrous to ferric chloride is my bet.

The process could have generated free chlorine which could give a yellow color to the solution, however if there was bromine comtamination that can easily give a orange color in small concentrations and would easily be formed from Br- in that enviorment.

Isn't that a sort of greenish-yellow, like with normal NaOCl bleach?

I was thinking that the oxygen from th h2o2 mights transfer to the HCl to form chloric(I, III, V, IV) acid, but i didnt think that they had any charachteristic colour.

Are you by any chance talking about "diggers" HCl?

its not diggers but its probably fairly similar in quality and purity. I get it from a pool chemical shop. (~37%)

When school starts again i am going to try this with AR grade HCl and H2O2 and see what happens.
