Chemical Equation

Chemical equations:

A Chemical Equations is the shorthand form of representing a chemical reaction using symbols and formula. The element/compounds involved in the reaction are called reactants and the new elements/compounds formed are called the products. Steps to write the chemical equation:

1)    Identify the reactants and the products of the chemical reaction.

2)    Write the names of the reactants on the left hand side & products on the right hand side with a ‘+’ sign between them. Place arrow (--à) between the two sides. This equation is called word equation.

3)    Replace the names of the products and reactants with symbols & formulae. This gives chemical equation.

4)    The number of atoms of each element should be equal on both sides & This is called balancing the equation.

Crystallization: Crystals are the purest solid form of a substance having a definite geometrical shape. The process by which an impure compound is converted into its crystals is known as crystallization. This process is used in obtaining common salt from seawater.
