  • Comment écrire l'équation bilan d'une réaction d'oxydation d'un alcool ?

    - et l'alcool primaire de formule R – CH2OH.
    Remarque : Il en est consommé 16 H+ (8 x 2), il se forme 10 H+ (2 x 5), le bilan donne 16 – 10 = 6 H+ consommés. x 4.
    Remarque : Il en est consommé 32 H+ (8 x 4), il se forme 20 H+ (4 x 5), le bilan donne 32 – 20 = 12 H+ consommés.

  • Quel alcool reagit avec le dichromate de potassium ?

    Quel réactif pourrait oxyder un alcool en carbonyle ? Le permanganate de potassium ou le dichromate de sodium, ce sont des agents oxydants puissants convertissant l'alcool primaire en acide carboxylique.

  • Comment se fait l'oxydation ménagée ?

    L'oxydation ménagée peut se faire par un oxydant doux, comme l'ion permanganate en solution aqueuse (K+ + MnO4-) ou par le dioxygène de l'air (sans combustion).
    Il existe d'autres oxydants doux (dichromate de potassium, trioxyde de chrome) mais ils sont plus toxiques.

  • Le chrome y est au 6e état d'oxydation.

Le dichromate de potassium est en particulier utilisé dans les éthylotests. En effet, l'éthanol est un alcool primaire qui, en présence d'un excès d'oxydant, s'oxyde en acide acétique selon la réaction : 3 CH
