What is formed whem Sulfur dioxide reacts with water?
Sulphurous acid is formed when sulphur dioxide dissolves in water. Sulphuric acid is formed when sulphur trioxide dissolves in water. Over time, sulphurous acid will oxidize to sulphuric. SO2 + H20 -> H2SO3 (sulphurous acid) SO3 + H20 -> H2SO4 (sulphuric acid)
Is so3 acidic or basic?
SO3 is an acidic oxide. It reacts violently with water to form sufuric acid, H2SO4
Can ninety two percent sulfuric acid prepared by adding liquid SO3 to eighty four percent sulfuric acid?
Yes, BUT... Liquid SO3 is HIGHLY reactive and not readily available. Pure SO3 reacts readily (and violently) with water or sulfuric acid. To manufacture sulfuric acid, dilute gaseous SO3 is absorbed in sulfuric acid to increase the concentration of the acid. 100% sulfuric acid can still absorb more SO3. When extra SO3 is dissolved in 100% H2SO4 (sulfuric acid) the solution is called oleum or fuming sulfuric acid. In general, oleum is used when free SO3 is required.
Is SO3 a Lewis base or Lewis acid?
I think it is acid, because there is a question that asks the acid site of SO3.
Why is SO3 insoluble in water but soluble in sulphuric acid?
Like dissolves like.
How is formed in the atmosphere?
The burning of coal or oil rich in sulpher releases SO3 to the atmosphere. This combines with water to form Sulpheric acid a strong acid. SO3 + H2O -> H2SO4

What is the chemical equation for aid rain?
Acid rain is formed when SO3 dissolves in water, i.e. in droplets that form clouds. As a product H2SO4 is formed. Since SO3 is produced in areas with heavy industry, thus these areas are under particular danger of acid rain. So, instead of pure rainwater, diluted H2SO4 falls on the ground. Acid rain is not a compound so it has no chemical formula. Equation: SO3(g) + H2O(l) ---> H2SO4(aq) Luck!
Why is SO3 insoluble in water but soluble in sulphuric acid?
Like dissolves like.
What is olium?
Olium is a gas which is formed when you mix SO3 with 98% H2SO4. It's chemical name is Pyrosulphuric Acid.
Is SO3 an acid?
Not in and of itself, but it readily reacts with water to form sulfuric acid, H2SO4
H20 plus so3?
H2O + SO3 --> H2SO4 The product is sulfuric acid.
How does sulphuric acid get in to rain?
Sulphur Dioxide is a a by-product of (mainly) powerstations that burn fossil fuels to produce the steam ofr the turbines. Sulphur Dioxide combines with water in the atmosphere to produce Sulphuric acid - which falls as 'acid rain. The chemical process is... SO2 + OH → HOSO2 - which is followed by... HOSO2 + O2 → HO2 + SO3 In the presence of water, sulphur trioxide (SO3) is converted rapidly to sulphuric acid... SO3 + H2O → H2SO4
Does sulfur dioxide react with air?
Sulfur dioxide (SO2) can react with the oxygen in the air to produce sulfur teioxide (SO3). Either of these gases can react with water in the air to produce an acid, goes to SO2 sulfurous acid, SO3 goes to sulfuric acid.
