Detailed information about the equation Fe + 2H2SO4 -> Fe2(SO4)3 + H2:
-
Reaction conditions:
-
For the reaction to occur, there needs to be contact between iron and sulfuric acid.
-
The sulfuric acid needs to be in a concentrated form.
-
The reaction will occur more effectively at high temperatures.
-
-
Reaction process:
-
When iron comes into contact with sulfuric acid, iron is oxidized to iron (III) and the sulfuric acid is reduced to hydrogen.
-
The essence of the reaction is the displacement between the iron ion and the hydrogen ion in sulfuric acid.
-
-
Observed phenomena:
-
When the reaction occurs, iron will dissolve in sulfuric acid.
-
We will see hydrogen gas rising.
-
After the reaction, the solution will contain iron (III) sulfate, which is reddish-brown in color.
