The above chemical equation describes the oxidation process of the metal Indium (In) with Oxygen (O2) to form Indium(III) oxide (In2O3). Accordingly, 4 moles of Indium react with 3 moles of Oxygen to produce 2 moles of Indium(III) oxide.
- Reaction conditions
This reaction usually occurs at high temperatures, when there is excess Oxygen and high Oxygen gas pressure.
- Reaction process
When Indium is heated in the air at high temperatures, Indium will react with Oxygen to form Indium(III) oxide. This reaction can also occur when Indium comes into contact with steam at high temperatures.
- Phenomena that occur
When the reaction occurs, there will be a phenomenon where the metal Indium begins to melt, transitioning from a solid state to a liquid state. Next, as the temperature increases, Indium will continue to react with Oxygen to produce Indium(III) oxide, leading to the appearance of the white solid substance of Indium(III) oxide.
