Hydrogen

This topic deals with the concept of dihydrogen along with its occurrence in detail. We will also learn the three major isotopes of dihydrogen, atomic and physical properties of hydrogen in a tabular form.

In this topic, we will study the preparation of dihydrogen in laboratory and commercial production of dihydrogen in detail. We will also go through the concept of syngas and coal gasification in brief.

In this topic, we will learn the physical and chemical properties of dihydrogen. It describes the reaction of dihydrogen with halogens, dioxygen, dinitrogen, organic compounds, metal ions and metal oxides. It also covers the uses of dihydrogen.

The topic introduces the concept of hydrides. It explains the three categories of hydrides-ionic or saline hydrides, covalent or molecular hydride and metallic or non-stoichiometric hydrides.

In this topic, we will study the estimate of world water supply, taste, colour, odour, boiling point, freezing point and various other physical properties in detail. We will also see the structure of water through a diagram.

In this topic, we will explore the meaning of hard water and soft water in brief. We will also see how hard water forms precipitate with soap through a chemical reaction and which among hard and soft water is unsuitable for laundry.

In this topic we shall learn the concept of preparation of hydrogen peroxide along with its various physical properties, structure, chemical properties, storage and uses in detail.

This topic deals with the concept of heavy water and its use as a moderator in nuclear reactors. We will also discuss the preparation of heavy water in industries for various purposes.

In this topic, we will learn about the properties of dihydrogen. It also explains the concept of the hydrogen economy, the harmful effects of the combustion of dihydrogen and its uses.
