Oxygen is in the air we breathe and in the ozone that shields us from the sun. Sulphur makes the acid that is used in the largest amount in industry. We study the oxides, ozone and its layer, the forms of sulphur, sulphur dioxide, the contact process and the acids of sulphur. It covers the Indian syllabus (NCERT, NEET, JEE Main) and the matching topic of A-Level, IB and AP.

You breathe oxygen, and a candle burns in it. A little way down the same column of the periodic table is sulphur, which is a yellow solid. We study how group 16 changes from oxygen to polonium, why oxygen is different, how it is made, and how its oxides are sorted.
Ozone protects us from the sun and also harms the lungs near the ground. Sulphur forms rings, and burning it gives a gas with a sharp smell. We study ozone and its layer, the forms of sulphur, and the properties of sulphur dioxide.
More sulphuric acid is made than any other chemical. We follow the contact process step by step, see why the plant uses 720 K and a catalyst, learn what the concentrated acid does, and read the oxoacids of sulphur.
