What reaction occurs when benzene is mixed with equal amounts of sulphuric and nitric acid?

Intro:This is an electrophilic substitution reaction (nitration)Nitric acid and sulphuric acid are used to create the electrophile (NO₂⁺)The electrophile then substitutes itself with a H atom on the benzene ring
Formation of the electrophile:Nitric acid is weaker than sulphuric acid, therefore it acts as a base in the reactionH₂SO₄ + HNO₃ = H₂NO₃⁺ + HSO₄^-H₂NO₃⁺ = H₂O + NO₂⁺NO₂⁺ is the electrophile - it attacks the delocalised ring of electrons in benzene[demonstrate mechanism of electrophile formation]
The Reaction:C₆H₆ + H₂SO₄ + HNO₃ = C₆H₅NO₂ + H₂O + H₂SO₄The sulphuric acid is a catalyst, therefore it is re-formed[demonstrate mechanism of main reaction]
