Proper name of this compound is Disulfuric acid
You have answered the question for yourself. The scientific name is 'Sulphuric Acid' . It known universally as sulphuric acid. The US spelling is 'sulfuric acid'. The formula is 'H2SO4'. Do NEITHER confuse with 'sulphurous acid'. This is an entirely different substance. Its formula is 'H2SO3'. NOR 'fuming sulphuric acid (oleum) , the formula is 'H2S2O7' .
Dissolution of SO3 in water. to form sulphuric Acid. Industrially, sulphur trioxide is dissolved in sulphuric acid to form oleum. Oleum ( fuming sulphuric acid) is seriously nasty stuff. SO3 + H2SO4 = H2S2O7 The oleum is then slowly dissolved in water to form sulphuric acid of the given molarity(strength). H2S2O7 + H2O = 2H2SO4 It is done this way in order to prevent 'spitting and fuming'. added to which you form twice a mush sulphuric acid.
The traditional name for fuming sulfuric acid is Oleum. Oleum is used for in water based aerosol coatings. Rust-Oleum has the fuming sulfuric acid in its name and hold many patents on its usage.
The systematic name for sulphuric acid is sulfuric acid.
The product is Disulphuric acid. Its other name are Pyrosulfuric acid, Fuming sulphuric acid and Oleum. Its formula is H2S2O7 . Its salts are called Disulphates and contain the S2O7-2 anions. It decomposes in water to produce Sulphuric acid.Sulphuric acid + Sulphur trioxide ----> Disulphuric acidH2SO4 + SO3 ----> H2S2O7 (already balanced equation)
oleum
As the name , 'Sulphuric Acid' suggests, it is an ACID .
