Sulfurous mountain Definition
Sulfurous acid is a chemical compound which has actually a formula H2SO3, and also is a weak and also unstable acid, formed when sulfur dioxide disappear in water. The facts that sulfur dioxide actually exists in solution, cannot be stated surely, however the molecule of this substance has actually been detect in the gas phase. That is a reducing, and also a bleaching agent. The sulfurous mountain compound is only formed in the aqueous solution, and also is because of this not isolated in that is pure state.

Sulfurous mountain Formula
The chemical formula of Sulfurous acid is H2SO3. This is the Sulfurous mountain Chemical formula, since it atom of hydrogen, oxygen and also carbon space joined by a strong chemical bond. This is additionally the molecule formula for sulfurous acid, since it demonstrates that one molecule that sulfurous acid contains two atom of hydrogen, one atom that sulfur and three atom of oxygen.
Sulfurous acid Physical Properties
Sulfurous acid is also known as sulfur dioxide solution. That is no an organic acid. That is a clear and also colorless solution.
Sulfurous acid Physical State
In the regular physical state, Sulfurous acid is a colorless liquid. That is appreciably dissolve in water, and ignites automatically at a particular temperature. The is a typically stable acid, and also is not compatible with solid bases.
Sulfurous acid Boiling Point
The boiling point of sulfurous mountain is -60 °C or 213 k.
Sulfurous acid Odor
Sulfurous acid has a sort of sulfurous odor.
Sulfurous acid Vapor Pressure
Its vapor pressure is 1740 kPa at around 21 °C.
Sulfurous acid Weight
The formula load of this acid is 82.07 amu (atomic fixed units).
Sulfurous mountain Density
The thickness of sulfurous mountain is 1.03 g/cm3, or 1.03 X 103 kg/m3.
Sulfurous mountain Acidity
The acidity of sulfurous acid is 1.5 ~ above the pH scale. That is not a really weak acid, but not a solid acid as well.
Sulfurous acid – strong or Weak
Sulfurous mountain is a weak and dibasic acid, and also it corresponds to the +4 oxidation state that sulfur. This mountain id known to type only in the dilute aqueous solutions, and also does not occur in other state. When this acid is exposed come atmosphere, that is changed to the strong sulfuric acid. This acid is basically formed due to the incomplete disassociation of strong sulfuric acid in the aqueous solution.
Sulfurous acid Decomposition
Sulfurous mountain is thermodynamically unstable. That decomposes and also disassociates into its chemistry constituents. This acid likewise decomposes as soon as that is formed. The decomposition reaction the sulfurous mountain is:
H2SO3 (aq)—–> H2O(l) + SO2(g)
Sulfurous mountain Equation
Since sulfurous mountain is a weak acid, it transforms to sulfuric acid on exposure to atmosphere. The Sulfurous mountain equation is as follows:
2H2SO3 + O2 —–> 2H2SO4
Sulfurous acid Uses
Sulfurous acid is a very solid reducing agent. It additionally acts together a bleaching agent due to the fact that it has some bleaching properties. There are particular substances that space injured by chlorine. These substances room bleached when they room exposed to sulfurous acid.

Sulfurous acid Effects
This acid normally does no exist independently, other than for aqueous solutions. As such it is not harmful in regular circumstances, since it does no exist independently. But it is convert to sulfuric mountain on exposure to atmosphere, and also this acid had plenty of harmful effects. This sulfuric mountain combines with rain to kind the harmful mountain rain. Acid rain is not only harmful for life, but for plants as well.
