What is H2SO3?
Sulfurous acid (H2SO3) is a weak, diprotic acid formed when sulfur dioxide (SO2) dissolves in water. It is a colorless liquid with a pungent odor. It is a weak acid, with a pKa of 1.82.
H2SO3 is a reducing agent and can be oxidized to sulfuric acid (H2SO4) or sulfurous acid (SO2). It is also a dehydrating agent and can remove water from organic compounds.
H2SO3 is used in a variety of industrial applications, including:
- As a bleaching agent in the paper industry
- As a preservative in food and beverages
- As a reducing agent in the chemical industry
