AQA Content
Explain the trend in the melting point of the oxides of the elements Na–S in terms of their structure and bonding
Explain the trends in the reactions of the oxides with water in terms of the type of bonding present in each oxide
Write equations for the reactions that occur between the oxides of the elements Na–S and given acids and bases.
Specification Notes
The reactions of Na and Mg with water.
The trends in the reactions of the elements Na, Mg, Al, Si, P and S with oxygen, limited to the formation of Na2O, MgO, Al2O3, SiO2, P4O10, SO2 and SO3
The trend in the melting point of the highest oxides of the elements Na–S
The reactions of the oxides of the elements Na–S with water, limited to Na2O, MgO, Al2O3, SiO2, P4O10, SO2 and SO3, and the pH of the solutions formed.
