- This is a typical reaction between iron (Fe), hydrogen peroxide (H2O2), and sulfuric acid (H2SO4) to produce iron (III) sulfate (Fe2(SO4)3) and water (H2O).
- Reaction conditions
-
To make the reaction occur, sufficient concentrations of H2O2 and H2SO4 are needed.
-
The reaction usually takes place at room temperature, but the reaction rate can be increased by raising the temperature.
- Reaction process
- Firstly, iron reacts with hydrogen peroxide to produce iron (II) and water.
- Next, this iron (II) reacts with sulfuric acid to produce iron (III) sulfate and water.
- Observations during the reaction
-
When the reaction occurs, the disappearance of the iron can be observed, and the color of the solution changes from transparent to dark brown (due to the formation of the Fe3+ ions).
-
Hydrogen gas and heat are generated, causing the solution to heat up.
-
The final solution containing iron (III) sulfate is dark brown in color.
