The sulfurous acid formula is H2SO3. That is a colorless weak dibasic acid, develops when sulfur dioxide is dissolved in water. The is the conjugate acid of hydrogensulfite.

Step 4: ar remaining electrons roughly the various other atoms

We have to distribute the sixteen continuing to be valence electrons. Hydrogen deserve to only save a preferably of two electrons. Sulfur and also oxygen have the right to contain eight electrons, so us add more electrons come them to complete the octet.

You are watching: What is the formula mass of sulfurous acid


Oxygen molar mass =15.9994 g/mol.Hydrogen molar mass = 1.00794 g/mol.Molar massive of Sulfur = 32.065 g/mol.Molar mass of H2SO3 = 2(1.00794)+32.065+3(15.9994)=82.06288 g/mol.


Uses of H2SO3

Good disinfecting agent.It is supplied to bleach paper products and also straw products, prefer bags and hats.

Is H2SO3 is a strong acid?

The pure anhydrous H2SO3 has actually never been isolated or detected. Sulfurous acid (H2SO3) is a weak acid; aqueous H2SO3 does not dissociate totally into H+ (H3O+) and also bisulfite ions, meaning that the bisulfite ion is comparatively more powerful in preserving a proton as soon as there is a base, such as water.The sulfurous acid chemical formula shows that it is one acid v oxygen atoms in its chemistry formula.


Sulfurous mountain formula is H2SO3It is a Weak not natural acidIts odor resembles Pungent burningsulfur.Upon heater at 150 levels Celsius, H2SO3 have the right to be decomposed right into Sulfuric acid, water, and also sulfur.It is a diprotic acid, consists of two donatable ions.The boiling allude of H2SO3 is -60 levels Celsius.It is discovered in mountain rain.

Frequently Asked inquiries (FAQs)

1. What is sigma bond?

In chemistry, sigma binding (bonds) space the strongest kind of covalent chemical bond. Atom orbitals colliding head-on create them. The symbol because that a sigma bond is σ

Sigma bonds space the strongest covalent bonds because the relevant orbitals are directly overlapping. Electrons are the electrons the are associated in developing a connection.

Sigma bonds space the the strongest covalent bonds because the relevant orbitals are directly overlapping. The electrons that are involved in a bond are known as electrons.


2. What is salt Sulfate?

The sodium salt that sulfuric acid is salt sulfate. It has the formula Na2SO4 and also is an not natural chemical.It is mainly utilized in the manufacturing of detergents and also in the Kraft procedure of document pulping. It exists in all develops as white solids that are really water-soluble. With an yearly output that 6 million tonnes, decahydrate is vital commodity chemical product.


Both Sulfuric acid and Sulfurous acid space diprotic acids, meaning they yield 2 protons ~ above dissociation. However, sulfuric acid is a strong acid because dissociation of the an initial proton is most favored in that as contrasted to H2SO3..
