H2SO3 is called Sulphurous Acid.
Understanding Sulphurous Acid
Sulphurous acid, with the chemical formula H2SO3, is a chemical compound that plays a significant role in various chemical processes. Here's a deeper look:
-
Chemical Names: Besides sulphurous acid, it's also known as:
- Sulphur dioxide solution
- Dihydrogen trioxosulphate
- Trioxosulphuric acid
-
Formation: It is an intermediate product in the formation of acid rain from sulphur dioxide (SO2). When sulphur dioxide dissolves in water, it forms sulphurous acid.
-
Importance in Acid Rain:
- SO2 + H2O ⇌ H2SO3
- This reaction is crucial in atmospheric chemistry.
- Sulphurous acid contributes significantly to acid rain.
- It undergoes further oxidation to form sulphuric acid (H2SO4), another major component of acid rain.
