pH=−log[H3O+]
[H3O+]=10−pH
[H3O+]×[HO−]=Ke avec : [H3O+] la concentration en ions oxonium ; 
[HO−] la concentration en ions hydroxydes ; Ke le produit ionique de l'eau.
pKe=−log(Ke) avec : Ke le produit ionique de l'eau.
p = m / V.
m : masse d'un volume V d'une substance ( kg.m-3 )
n = m / M

p.V = n.R.T.
n : quantité de matière ( mol ) ; V : volume occupé par le gaz ( m3 ) ; P : 
pression du gaz ( Pa ) ; R = 8,314 J.mol-1.K-1 ; T : température ( K )
T=Cf/Ci=Vf/Vi
