No, it is a weak acid.
Sulfuric acid, however is a strong acid
Sulfurous acid H2SO3 is a weak di-protic acid.
Sulfurous acid is the common name. That chemical is merely sulfur dioxide dissolved in water and is classified as a very strong acid.
Dihydrogen Sulfur Trioxide or sulfurous acid
Sulfurous acid: sulfite, (SO3)-2 Chlorous acid: chlorite, (ClO2)-
It will tell how acidic or basic (or how stable) sulfurous acid is.
Sulfurous acid H2SO3 is a weak di-protic acid.
Sulfurous acid is the common name. That chemical is merely sulfur dioxide dissolved in water and is classified as a very strong acid.
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.
Dihydrogen Sulfur Trioxide or sulfurous acid
H2SO4 is the chemical formula of sulphuric acid.
Sulfurous Acid is the name given to this solution. It cannot be isolated because the acid drives away the sulfur dioxide leaving water.
Sulfurous acid: sulfite, (SO3)-2 Chlorous acid: chlorite, (ClO2)-
It will tell how acidic or basic (or how stable) sulfurous acid is.
