What chemical property differentiates sulfurous acid from sulfuric acid?

Answer 1

Sulphur is a multivalent non-metal, abundant, tasteless and and odorless. In its native form sulphur is a yellow crystalline solid. In nature it occurs as the pure element or as sulfide and sulfate minerals. Although sulphur is infamous for its smell, frequently compare to rotten eggs, that odor is actually characteristic of hydrogen sulphide (H2S).

The crystallography of sulphur is complex. Depending on the specific conditions, sulphur allotropes form several distinct crystal structures.

Answer 2

. Sulphur dioxide is a colourless liquid or pungent gas, which is the product of the combustion of sulphur on air. Its melting point is -72.7 degC, its boiling point is -10 degC and its relative density is 1.43.

Answer 3

If it is high school, need to have the following 4 properties: combustion of sulfur dioxide in oxygen; and concentrated sulfuric acid reaction of sulfur dioxide and water; and the reaction of hydrogen sulfide gas; and alkali at room temperature, the reaction of sulfide, sulfite and water, for example, and sodium hydroxide at room temperature, the reaction of sodium sulfide, sodium sulfite and water.

Answer 4

Sulfurous acid contains sulfur in the +4 oxidation state, while sulfuric acid contains sulfur in the +6 oxidation state. This difference in oxidation state affects the chemical properties of the two acids, such as their acidity and reactivity with other substances.

Answer 5

it is highly flammable and have explosives property.

Answer 6

Sulfuric acid is a strong acid while sulfurous acid is relatively weak.

Sulfuric acid is H2SO4

Sulfurous acid is H2SO3
