Chemical Properties of Alkaline Earth Metals
As alkaline Earth metals have low ionization energies and high electropositive character, they are very reactive and have a strong tendency to lose valence electrons, though less than alkali metals. The reactivity of these elements increases on going down the..
By using alkaline pyrogallol
Take a glass tube with graduation from 0 to 100 ml. Close the lower end by a rubber stopper, and pour into it a saturated solution of sodium hydroxide up to the 0 mark. Add a few crystals of white pyrogallol (about 0.5 g) into the glass tube. Now close the upper end with a glass stopper, and then ..
Metals and Non-metals
Earth is an abundant source of material. Man has intensively studied the properties of these materials extensively and found new methods of using them. The air we breathe, the water we drink, stones and rocks, almost everything that is around us, are all useful t..

The Earth's Magnetism
A magnetic compass was used to help the sailors for navigational purpose. But recently it has been discovered that some migrant birds have magnetic sensors in their heads, which help to guide them using the Earth's magnetic field. William Gilbert suggested that Ea..
