acide:libere H+ (gain dun h+)
base:capte H+ (perte dun h+)

AH -><- A- + H+ (couple acide-base)

L'eau est une espece amphotere

H3O+/H20
H2O/HO-

H2CO3/HCO3-
CO2,H2O/HCO3-

R-COOH/R-COO-
R-CO2H/R-CO2-

acide carboxylique peut liberer un H
par rupture de la liaison polarisee 
O-H (car Xo>Xh)

Amine primaire R-NH3+ / R-NH2
secondaire R- NH2+ -R, / R- NH -R,
tertiaire R - NH+ - R, / R- N -R,
              - R,,    /   -R,,
Amine est base car il y a DNL a N2

pH = -log ([H3O+] / C0)
          mol.L-1   1.0mol.L-1
          
[H3O+] = C^0 * 10^-pH

pH augmente qd [] diminu et inverse
pH metre -> incertitude de 0,1

A1H/A1-
A2H/A2-
-> A1H + A2- -><- A1- + A2H
