Here is my logic:
Assume the reaction produces iodine and chlorine:
2HIO
3+10HCl(conc)
I
2+5Cl
2+6H
2O
I know, that Iodine and chlorine can react at 25 °C:
I
2+3Cl
2 2ICl
3I also know that ICl
3 can react with conc. HCl and water:
4H
2O + ICl
3 HICl
4·4H
2O
Summing up the reactions:
HIO
3 + 6HCl(conc., excess) + H
2O
HICl
4·4H
2O + 2Cl
2Can it be true? If someone has access to SciFinder, could you please look up this reaction?
Or maybe it just stops on chlorine and iodine, i don't know. In the flowchart they mention excess HCl.. that's why I want to suggest HICl
4·4H
2O as the product
