or melting together
Al2O3+2NaOH=2NaAlO2+H2O
The chemical formula for aluminum oxide is Al2O3.
Hydroxide ions are negatively charged particles made up of one oxygen atom and one hydrogen atom.
The reaction between Al2O3 and hydroxide ions is a neutralization reaction, where the acidic Al2O3 combines with the basic hydroxide ions to form a salt and water.
The balanced equation for this reaction is: Al2O3 + 6OH- → 2Al(OH)3. Note that the charges must be balanced on both sides of the equation.
The products of this reaction are aluminum hydroxide (Al(OH)3) and water (H2O).
