Superhape

Superhape on hape, mille Hammeti happelisuse funktsioon (H₀) on suurem kui puhtal väävelhappel. Väävelhappe väärtus Hammeti happelisuse skaalal on −12.^[1] Kaasaegsema määratluse kohaselt on superhappega tegemist siis, kui selle prootoni potentsiaal on suurem kui puhtal väävelhappel.^[2] Superhappeid saadakse kombineerides omavahel tugeva Lewisi happe ja tugeva Bronstedi happe. Kaubanduses on kättesaadavad näiteks trifluorometaansulfoonhape (CH₃SO₃H) ja fluorosulfoonhape (HSO₃F), mis on mõlemad negatiivsema H₀ väärtusega ja umbes tuhat korda tugevamad kui väävelhape.
