un acide perd un proton et un ion H+
une base gagne un proton
couple acide base =AH/A-

masse molaire  M = g/mol 

quantite de matiere n=m/M  m en g M EN g/mol
ou aussi m= M*n  n en mol

concentration mol/L  c=n solute / V solution
n mol et v L

pour savoir la quantite de matiere dun solute en solution
n solute= V solution x c

Si on nous demande de calculer le pH il faut utiliser la relation
pH = log(H3O+)

Si on nous demande de calculer la concentration en quantité de matiere 
d ions oxonium il faut utiliser la relation H3O+ = 10pH

Si pH < 7, alors [H3O+] > [HO-] et la solution est acide
Si pH > 7, alors [H3O+] < [HO-] et la solution est basique
Lorsque [H3O+] = [HO-], le pH = 7 et la solution est neutre
