Sodium Chlorate

Sodium chlorate is an inorganic compound that has the consists of the sodium and chlorate. Yearly it produces the millions of tones for using the many applications in the industry oriented. At the temperature of above 300C it releases the oxygen. It is hygroscopic in nature. It converts from the pale yellow to white crystalline solid.The systematic IUPAC name is known as sodium chlorate . The chemical or molecular formula of sodium chlorate is NaClO3. It is also known as sodium chlorate (V).

Structural Formula

This is the structural formula of the sodium chlorate:

Sodium Chlorate

Molecular  Formula

The chemical or molecular formula of the sodium chlorate is NaClO3.

How the Sodium Chlorate is Prepared

The sodium chlorate can be prepared by the electrolysis concentrated reaction. When the sodium chloride is reacted with the water it will produces the sodium chlorate as the product and hydrogen as the byproduct. In this process the sodium acts as the cathode and chloride acts as the anode. It transfers the free electrons along with the reaction between these two chemicals. The chemical reaction is as follows.
