In the reaction to get I2 from an aqueous solution of KI.
The process. Take the aqeuous KI, and pour concentrated hydrochloric acid, followed by hydrogen peroxide.
K++I-+H++Cl-+H2O[itex]\rightarrow[/itex] KCl + HI + H2O
The reaction with H2O2 is perplexing.
I'm a physics student trying to do chemistry, I'm sure I made some mistake in writing out that chemical equation (I forgot if ions have to be separated in the equation, when in a solute).
What are the specifics of this chain of reactions? The elemental iodine will precipitate out of solution. The H2O2 must be oxidizing something in the K+ + Cl- + H+ + I- + H2O
