The image shows a colourless solution of hydrogen peroxide.
Click to see what happens when an iron chloride(III) solution has been added!
After adding a solution of iron(III) chloride :
$2H_2O_2$ $\longrightarrow $ $ 2H_2O $ $+ $ $ O_2 $
Oxygen gas is liberated, iron(III) chloride is returned in full at the end of reaction (see colour!)
