Some common acids that are found in laboratories are Hydrochloric acid (HCl), Sulphuric acid (H 2 SO 4 ) and Nitric acid (HNO 3 ). Some of the lesser used acids are Acetic acid (CH 3 COOH), Hydrofluoric acid (HF), Carbonic acid (H 2 CO 3 ). Hydrofluoric acid is a highly corrosive acid an..

In the manufacture of soap, paper, viscose rayon (artificial silk), organic dyestuffs, and many other chemicals In the refining of petroleum and vegetable oils In the purification of bauxite for the extraction of aluminium As a cleansing agent and in washing powder for machines, metal sheets e..

Acids, bases and salts are three main categories of chemical compounds. These have certain definite properties which distinguish one class from the other. The sour taste of many fruits and vegetables, lemon for instance, is due to various types of acids present in them. The digestive fluids of mos..

New species can be created by domesticated animal husbandry for better and yield. For example, a new species of domestic sheep were created by hybridisation that no longer produced viable offspring with the parent species. Domestic cattle on the other hand, with several varieties such as jersey, h..

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 presence of water on the surface of a metal. Iron corrodes more quickly than most other transition metals to form an iron oxid..

An element is defined as a pure substance as it is made up of only one kind of atoms having the same atomic number. The smallest particle of an element is the atom, which has all the properties of that element. It cannot be further reduced to simpler substances by ordinary physical or chemical pro..

Elements of group I A of the periodic table constitute a family of very reactive metals called alkali metals. They are lithium, sodium, potassium, rubidium, caesium and francium. All of them have one electron in the valence shell. They are called alkali metals because their hydroxides are strong a..

. Metals above carbon cannot be extracted by carbon reduction and are usually extracted by electrolysis. Metals below hydrogen will not displace hydrogen from acids: Metals Reactivity and reactions Potassium K Very reactive, very rapid with cold water forming the alkali potassium hydroxide and hydr..

Summary - Science is the way by which a person gets at the truth or at least as close to truth as possible. The basis of science is its orderly stepwise procedure - the scientific method. Scientific method employs various procedures such as, accurate observation, asking question..
