Answer

Action of Alkalis — on oxides and hydroxides of certain metals

Zinc oxide ZnO + 2NaOH ⟶ Na2ZnO2 + H2O
Zinc hydroxide Zn(OH)2 + 2NaOH ⟶ Na2ZnO2 + 2H2O
Lead [II] oxide PbO + 2NaOH ⟶ Na2PbO2 + H2O
Lead hydroxide Pb(OH)2 + 2NaOH ⟶ Na2PbO2 + 2H2O
Aluminium oxide Al2O3 + 2NaOH ⟶ 2NaAlO2 + H2O
Aluminium hydroxide Al(OH)3 + KOH ⟶ KAlO2 + 2H2O
