Une échelle de teintes en colorant E133 a été préparée par dilution mère. les concentrations en masses du colorant son indiqué ci-dessous. (échelle de teintes) : tube a: 4mg. L^-1
tube b: 6mg. L^-1
tube c: 8mg. L^-1
tube d: 10mg. L^-1

(Solution d'Alodont) :

t=?

Dans un tube a essai identique à ceux de l'échelle de teintes, on verse une solution d'Alodont contenant le colorant E133.

1) Nommer la méthode permettant de déterminer la concentration en masse de l'espèce coloré

2) Estimer la concentration en masse t en colorant E133 de la solution d'Alodont.
