The equation NaOH + Al2O3 -> NaAlO2 + H2O

1. Detailed Information:

Chemical equation: 2NaOH + Al₂O₃ -> 2NaAlO₂ + H₂O

In the above equation, two molecules of sodium hydroxide (NaOH) react with one molecule of aluminum oxide (Al₂O₃) to form two molecules of sodium aluminate (NaAlO₂) and one molecule of water (H₂O).

2. Reaction Conditions:

This reaction requires the presence of high temperature and high pressure to occur.

3. Reaction Process:

When NaOH is heated with Al₂O₃ at high temperature and high pressure, it will produce NaAlO₂ and H₂O. In this process, Al₂O₃ will enhance the basicity of NaOH, helping to create NaAlO₂.

4. Observed Phenomena:

The reaction will end when no more gas bubbles are visible, and the mixture will become transparent. The sodium aluminate compound (NaAlO₂) created has a liquid form, is white in color, and is characterized by its strong alkalinity. The reaction also produces water as a by-product.
