Learning outcome 9.1(g) and part of 9.1(j)
This statement - 9.1(g) - deals with the reactions of the oxides of the elements in Period 3 with water. 9.1(j) is involved in the explanation for this.
Before you go on, you should find and read the statements in your copy of the syllabus.
Remember that we are only dealing with the oxides:
Na2O, MgO, Al2O3, SiO2, P4O10, SO2 and SO3.
The reactions between these oxides and water are found on the page acid-base behaviour of the period 3 oxides. That page contains a lot of information, and if you try to absorb it all in one go, you risk getting really confused.
For each oxide, you will find an introduction, its reaction with water (if any), and its reaction with acids or bases. For the purposes of this statement, just read the introduction to each oxide, and its reaction with water. Ignore everything else!
Remember that you don't need to know about phosphorus(III) oxide, or the oxides of chlorine.
