Na2O Sodium Oxide is a baseNa2O + H2O

–> 2NaOH MgO Magnesium Oxide is a baseMgO + H2O –>

Mg(OH)2 Al2O3 Aluminium Oxide is amphoteric (can act as acid or a

base)As a base: Al2O3 + 6HCl –>

2AlCl3 + 2H2OAs an acid:

Al2O3 + 6NaOH + 3H2O –>

2Na3Al(OH)6 SiO2 Silicon Dioxide is acidicSiO2 + 2NaOH

–> 2Na2SiO3 + H2O P4O10 AcidicP4O10 + 6H2O

–> 4H3PO4 SO2 AcidicSO2 + H2O –>

H2SO3 SO3 AcidicSO3 + H2O –>

H2SO4
