Investigating the properties of period 3 oxides.

Formula of oxides: Na2O2, MgO, Al2O3, SiO2. P4O10, SO2, Cl2O.
the solubility in hexane is want to knw whether can disolve in organic solvent and the action of water is state whether disolve/ soluble/ insoluble.

oh right, check the electronegativity of the elements vs oxygen.
Na = 0.93
Mg=1.31
Al=1.61
Si=1.90
P=2.19
S=2.58
Cl=3.16
O= 3.44
as you approach the Cl, you get more covalent, less polar bonding. Only non-polar bonds will dissolve

Non-polar covalent bond: 0.0-0.4
Slightly polar bond: 0.5-0.9
Moderately polar bond: 1-1.3
Highly polar bond: 1.4-1.7
Slightly ionic bond: 1.8-2.2
Ionic Bond: 2.3+

Solubility is maximum for SiO2 and falls down as we go the right and the left.

Water forms storng bases with Na2O2 and MgO

No effect on SiO2

Acids produced with P4O10, SO2, Cl2O.

Amphoteric action with Al2O3.

Only the last three are soluble in hexane, showing their covalent simple molecular character.
Na - very soluble in water ---> alkaline solution
Mg - marginally soluble - weakly alkaline solution
Al & Si - insoluble
P, S and Cl - soluble to form acidic solutions.
