Investigating the properties of the period 3 oxides.
oxides: Na2O2, MgO, Al2O3, SiO2, P4O10, SO2, Cl2O
Answer:
Basic (Na2O and MgO), amphoteric (Al2O3) to acidic (the rest).
starts basic (the first 2) and becomes more and more acidic
Solubility is maximum for SiO2 and falls down as we go the right and the left.
Water forms strong bases with Na2O2 and MgO
No effect on SiO2
Acids produced with P4O10, SO2, Cl2O.
Amphoteric action with Al2O3.
