    MgO basic MgO + H2SO4 --> MgSO4 + H2O

    Al2 O3 amphoteric

    basic Al2O3 + 6HCl --> 2AlCl3 + 3H2O

    acidic Al2O3 + 2NaOH + 3H2O --->2 NaAl(OH)4 [sodium tetrahydroxoaluminate]

    P4 O6 acidic reacts with cold water to give phosphonic acid, H3PO3, and with hot water to give phosphine and phosphoric(V) acid
