Il faut préciser l'acide sulfurique. le pKs(H2SO4) est -3, pks(HSO–4) = 1.92.
Quelles des affirmations suivantes sont exactes? Et, plus important encore, pourquoi?- c(H2SO4) > c(HSO–4 ) > c(SO2-4 )
- c(HSO–4) > c(H2SO4) > c(SO2-4)
- c(H2SO4) = c(HSO–4) > c(SO2-4)
- c(HSO–4) > c(SO2-4) > c(H2SO4)
- c(SO2-4) > c(HSO–4) > c(H2SO4)
