demi equation :
  -ecrire ox a gauche et red a 
  droite+ double fleche
  -equilibrer H et O
  -equilibrer H2O
  -equilibrer les charges elec
couple 1 : ox1/red1
couple 2: ox2/red2
ox1+red2=>red1+ox2

equivalence:
  aA+bB=>cC+dD
reactif titre:Ca inconnue, Va connu, 
reactif titrant:Cb connu, Vb connu
  
n0(A)/a=ne(B)/b
  n0(a)=quantiter de matiere de 
reactif titre introduit dans le 
becher
nE(B)= quantiter de matiere
de reactif verse dans le becher 
apres equivalence
  
CA*Va/a=CB*VE/b
  on connait le volume B verse
dans le becher a equivalence 
grace a la burette graduer. 
on note ce volume VE

CA=a/b*CB*VE/VA

loi de beer lambert 
A=K*C soit A=E*l*C
A=sans unité
E=L.mol-1.cm-1
l=Cm
C=mol.l-1

la couleur est l'oppose de imax
