Differbetween
SO2 is sulfur dioxide, and SO3 is sulfur trioxide. Both are oxides of sulfur. The key difference between SO2 and SO3 is that SO2 is a colorless gas at room temperature, whereas SO3 is a colourless to white crystalline solid.

Why is SO2 formed instead of SO3?
Since they are formed by the interaction between sulphur and O2 molecules, these compounds are called sulphur oxides. The key contrast between SO2 and SO3 is that SO2 has two atoms of oxygen bonded to a sulphur atom, whereas SO3 has three atoms of oxygen bonded to a sulphur atom.
Which is more acidic SO2 or SO3?
Acidity is determined by the stability of the conjugate base of the acid. In this case for SO3, it is SO−3, for SO2, it is SO−2. ... Hence, SO3 is a stronger acid.
How is Sulphur dioxide changed into Sulphur trioxide?
Burning coal, oil, and gas can create the pollutant sulfur dioxide. Over time, this pollutant will turn into sulfur trioxide, which can react with water in the air and form acid rain. The reactions to make either of these are exothermic, oxidation reactions.

How is SO2 formed?
Sulfur dioxide, SO2, is a colorless gas or liquid with a strong, choking odor. It is produced from the burning of fossil fuels (coal and oil) and the smelting of mineral ores (aluminum, copper, zinc, lead, and iron) that contain sulfur. Sulfur dioxide dissolves easily in water to form sulfuric acid.
Why is SO2 not so?
Oxygen is naturally diatomic, and the process by which it oxidizes sulfur is radical-based, leading to both oxygen atoms reacting. The fact that SO2 forms instead of SO is a result of the [redundant answer] thermodynamics favor SO2 over SO. ... Hence SO2 should be a better structure than SO overall.
Is SO2 acidic or basic?
Sulfur dioxide is one of the few common acidic yet reducing gases. It turns moist litmus pink (being acidic), then white (due to its bleaching effect).
Can SO2 act as Lewis acid?
Hence sulphur being deficient in electrons can accept a pair of electrons. Hence SO2 is a Lewis acid.
Why SO3 is a Lewis acid?
Molecules with electron deficient atoms are strong Lewis acids. SO3 and CO2 are not electron deficient, but the central atom in each has less than four electron regions (three around S and two around C), so they are Lewis acids.
Is SO3 dangerous?
SO3 Safety. Sulphur trioxide is considered a poison. Inhalation of the vapours, swallowing the material of severe skin contact can result in death. Skin and eye contact causes severe burns and blindness.
What happens when Sulphur dioxide reacts with oxygen?
Formed by the reaction of sulfur dioxide and oxygen in the presence of catalysts, sulfur trioxide fumes vigorously in contact with moist air and dissolves in water, liberating much heat and forming sulfuric acid. Solutions of the trioxide in sulfuric acid are called fuming sulfuric acid, or oleum.
What does sulfur trioxide and water make?
Sulfur trioxide (SO3) is generally a colorless liquid. It can also exist as ice- or fiber-like crystals or as a gas. When SO3 is exposed to air, it rapidly takes up water and gives off white fumes. It can react with water to form sulfuric acid.
