I got an equation here but I can't damn recall how to finish it... some help plz...

 

[ce]MnO2 + HCl -> ?[/ce]

 

I know that this is a way to get elementary chlorine but that's it!

that would produce elemental hydrogen but not elemental chlorine.

 

you'd get managanese tetrachloride and hydrogen gas.

 

EDIT: actually, are you talking about Weldon process? if you do then you are missing some reactants.

No no, one of the ways of getting chlorine is the reaction between hydrochloric acid and substances with high oxidation features ([ce]KMnO4[/ce] or [ce]MnO2[/ce]).

 

You'd definitely get chlorine there.... but I'm stuck at what else?

 

edit:

 

one way is:

 

[ce]2KMnO4 + 16HCl -> 2KCl + 2MnO2 + 5Cl2 + 8H2O[/ce]

 

but what about with [ce]MnO2[/ce]
