Mechanistic study on the atmospheric formation of acid rain base on the sulfur dioxide.

The reaction pathways of acid rain formation from reaction of sulfur dioxide vapor and water vapor on the singlet potential energy surface have been investigated theoretically. The calculated results … Expand. Sulfur is the tenth most abundant element in the universe and is known to play a significant role in biological systems.

In the figure, one electron pair between two atoms is equivalent to one line covalent bond. Out of 26 electrons, 10 will be used in pairs between atoms. We need to distribute the 16 remaining valence electrons. Hydrogen can only contain a maximum of two electrons. Sulfur and oxygen can contain 8 electrons, so we add more electrons to them to complete the octet 8 electrons. Molar Mass of H 2 SO 3.

Important Links. Weak acids dissociate partially in the water, resulting in an equilibrium state containing the weak acid and its ions. The ability of an acid or basic to dissociate is measured using dissociation constants. These values are denoted as Ka for acids and Kb for bases. There are no units for these constants. Both Sulfuric acid and Sulfurous acid are diprotic acids, meaning they yield two protons on dissociation.

However, sulfuric acid is a strong acid because dissociation of the first proton is most favoured in it as compared to H2SO3. H 2 SO 3 is a Corrosive chemical. Any direct contact with it can severely irritate and burn the skin and eyes with possible eye damage. Breathing H 2 SO 3 can irritate the nose and throat. It is a colourless gas that has a high solubility in water. In solution, it hydrates to sulphuric acid H2SO3 , which in turn dissociates to form ions of bisulfite and sulfite SO2—3.

Reducing agents like Sulfurous acid H 2 SO 3 have the ability to take up oxygen from the air and other substances that are rich in oxygen.
