acid-base behaviour of the period 3 oxides - chemguide

4/10/2018· For the remainder of the oxides, we are mainly going to be considering the results of reacting them with water to give solutions of various acids. When we talk about the acidity of the oxides increasing as you go from, say, phosphorus(V) oxide to sulphur trioxide to chlorine(VII) oxide, what we are normally talking about is the increasing strengths of the acids formed when they react with water.
