- The equation Al2O3 + 2KOH -> 2KAlO2 + H2O
describes the chemical reaction process between aluminum oxide (Al2O3) and potassium hydroxide (KOH) to form potassium aluminate (KAlO2) and water (H2O).
- Reaction conditions: The reaction takes place in a water environment and at high temperatures. In addition, a sufficient amount of catalyst is needed to speed up the reaction.
- Reaction process: Aluminum oxide is diluted in water to form an acid solution. This acid solution is then mixed with a solution of potassium hydroxide. The result is the formation of a potassium aluminate solution and water.
- Observed phenomena: The observable reaction phenomenon is the color change of the solution, from the white color of aluminum oxide to the light yellow color of the potassium aluminate solution.
