The remaining 2 paired orbitals form the lone pair of sulfur. Sulfur requires 2 unpaired electrons from the sp 2 hybridized orbitals to form 2 sigma bonds with oxygen atoms. This, in turn, has 3 equivalent orbitals with 2 paired electrons and 2 unpaired electrons. Further, the 3s 2 and 3p 3 now unite to create sp 2 hybridization. 1 electron from the 3px orbital jumps to the 3d orbital when in an excited state. In the case of SO 2, the electronic configuration of the ground state is 1s 2 2s 2 2p 6 3s 2 3p 4. Likewise, it also acts as a reducing effect.It is neither combustible nor supports combustion.

Since SO2 dissolves in water to generate sulfurous acid, it has an acidic nature.

It is a colorless gas with a pungent smell of rotten eggs.

The characteristics of sulfur dioxide are as follows:

In the same vein, we can obtain sulfur dioxide when hot concentrated sulfuric acid reacts with copper turnings.

Sulphur dioxide is formed as a byproduct during the manufacture of calcium silicate cement.ĢCaSO 4 + 2SiO 2 + C → 2CaSiO 3 + 2SO 2 + CO 2.

The resulting gas is then dried, liquefied, and then stored in steel cylinders.ĤFeS 2 (s) + 11O 2 (g) → 2Fe 2O 3 (s) + 8SO 2 (g)

We can also obtain sulfur dioxide commercially as a by-product of the roasting of sulfide ores.

Na 2SO 3 + H 2SO 4 → Na 2SO 4 + H 2O + SO 2 Take the example of a reaction between dilute sulphuric acid and sodium sulfite.

Sulfur dioxide can be prepared by the reaction of metallic sulfite or metallic bisulfite with any dilute acid.

Now, we shall list a few methods of laboratory preparation of SO 2. Perhaps, it might also be found in liquid form, therefore reacting quickly with water. Also, it is available in the crust and mantle of Europa, Callisto, and Ganymede. Likewise, it is assumed as subliming frost or ice on Io’s trailing hemisphere. Thus, it is an important component of chemical reactions in the planet’s atmosphere, contributing to global warming.Īlso, when it comes to the Galilean moons, SO 2 is thought of existing as a block of ice. Besides, it is also the third-most significant atmospheric gas in Venus. Moreover, the most significant among them is the Venus atmosphere, which has a 150 ppm concentration of SO 2. Medvedev, V.A.Sulfur dioxide is present on the Earth in very small proportions in the atmosphere – at about 1 ppm.įurther, one can find SO 2 in varying amounts on many planets.
