This chemical equation describes the reaction process between copper (Cu) and potassium hydroxide (KOH) to produce copper(II) hydroxide (Cu(OH)2) and potassium (K).
- Reaction conditions:
This reaction requires high temperature and appropriate pressure to occur.
- Reaction process:
During the reaction process, the copper atom from Cu is transformed into copper(II) ion in Cu(OH)2, while the potassium atom from KOH is released as free potassium atom.
- Phenomena occur:
When the reaction occurs, we can observe a clear phenomenon which is the color change of the reaction mixture. When Cu and KOH react with each other, the color of the mixture changes from blue to green due to the formation of copper(II) hydroxide. At the same time, the potassium atoms released during this process also cause the reaction mixture to heat up.
