Describe about the Ferromagnetic materials
Ferromagnetic materials are those for which k susceptibility is large and positive. These are strongly attracted by magnetic field. Illustrations are iron, cobalt, nickel etc.
A significant feature of ferromagnetic materials is that they can retain their magnetism even after magnetising field has been removed, i.e. they can become permanent magnets.
Ferromagnetic materials are those with spontaneous magnetic alignment. Ferromagnetism is property of a material to be strongly attracted to a magnetic field and to become a powerful magnet.

Q. Analytical tests for fats and oils? The analytical tests used in fats and oils are to: • determine the nature of fat or oil or the blends to see whether it is of the typ
Q. What is Standard Enthalpy of Formation? Ans. It is really difficult to measure the total energy content or absolute entropy of a substance. In order to quantify entropy
Unlike components of the 3 d series, 4 d and 5 d elements have little simple aqueous cationic chemistry. The main exceptions are La3+ and Y3+, and Ag+, which builds some soluble
when H+ is removed from any compound it forms conjugate acid. the addition of H+ ion gives conjugate base.
