Corrosion can be prevented by applying a protective coating on the surface of the iron, so that the iron does not come in contact with air and moisture simultaneously. This coating can be of two types: (i) Non-metallic coating (ii) Metallic coating. Given below are some of th..

Many metals like iron, steel, polymers, ceramic etc are damaged due tosome natural process. Corrosion is one of them. The process of slowly eating away the metal due to attack of the atmospheric gases on the surface of metals, forming oxides, carbonates, sulphides is called corros..

Introduction: Any process of deterioration (or destruction) and consequent loss of a solid metallic material, through an unwanted (or unintentional) chemical or electrochemical attack by its environment, starting at its surface is called corrosion. The most familiar examp..

Iron (or steel) corrodes more quickly than most other transition metals and readily does so in the presence of both oxygen (in air) and water to form an iron oxide. Rusting is speeded up in the presence of salt solution. Rusting is Fe (s) + O 2(g) + H 2 O (I) Fe 2 O 3 . x H 2 O (5) i.e., r..

We have learnt that metals that are chemically active get corroded in the presence of a moist atmosphere. We have learnt that metals that are chemically active get corroded in the presence of a moist atmosphere. Corrosion is an oxidation reaction with atmospheric oxygen in the pres..

This is the most communicable disease in our country and effects mainly children in the age group 0-15 years. Every year 2.5 million people suffer from typhoid. Caused by bacterium salmonella typhi, it passes out through the excreta of the infected person. This is spread by houseflies or dire..

AIDS is a fatal disease in which the immune system of the body is affected. Acquired Immuno Deficiency Syndrome which is the medical expansion for AIDS was first detected in June 1981 in USA. The disease is caused by a retrovirus - HIV (human immuno deficiency virus). AIDS is a fatal disease..
