H2SO3, or sulfurous acid, is weak.

A quick way to verify the strength of acids with oxygen in them is to get the number of oxygen atoms (in this case, 3) minus the number of hydrogen atoms (in this case, 2); if the result is lower than 2, the acid is weak.

Is sulfurous acid a strong or weak acid or base?

Sulfurous acid H2SO3 is a weak di-protic acid.


Is sulfurous acid a strong acid?

Sulfurous acid is a weak acid. It is a relatively unstable compound that easily decomposes into sulfur dioxide and water. When dissolved in water, sulfurous acid only partially dissociates into hydrogen ions, making it a weak acid.

H2SO3 is an acid. It is a weak acid known as sulfurous acid.


Is sulfur dioxide an acid neutral or alkali?

Sulfur dioxide is an acidic gas that can dissolve in water to form sulfurous acid, which is a weak acid. Therefore, sulfur dioxide is classified as an acid.

What is the charge for Sulfurous acid?

Sulfurous acid (H2SO3) is a weak acid and can form sulfite salts. In its pure form, sulfurous acid does not exist as a stable compound. Rather, it is typically found in solution as a mixture of sulfite ions (SO3^2-) and bisulfite ions (HSO3^-).


What is H2S03?

H2SO3 is sulfurous acid, a weak acid that is formed by dissolving sulfur dioxide in water. It is a colorless liquid that is not very stable and easily decomposes to form sulfur dioxide and water.


Is H2SO3 a salt?

H2SO3 is the chemical formula of the sulfurous acid.


What is difference between H2SO3 and H2SO4?

The chemical difference is the oxidation state of sulfur, but only this makes a great difference in the allover chemical properties:H2SO3, sulfurous acid, oxidation state +4, weak diprotic acid, only stable in water, without it will decompose into sulfurous oxide (gas, SO2)H2SO4, sulfuric acid, oxidation state +6, strong (second protolysis is relatively strong) diprotic acid, hygroscopical with and very stable in water.


Is hypochlorous acid a strong or weak acid?

Hypochlorous acid is a weak acid. It is a fairly weak acid compared to strong acids like hydrochloric acid.


What does sulfur dioxide and water make?

Sulfur dioxide and water react to form sulfurous acid, which is a weak acid. The reaction is reversible and can go back and forth depending on conditions such as temperature and concentration.
