Resumen:
We study ionization and dissociation equilibria of hydrogen in typical conditions of magnetic white dwarfs, where magnetic fields can reach intensities ~10^9 G (Garcia-Berro et al. 2015) . We consider a gas constitued by H, H+, H-, H2, H2+ and free e-. In this context, equilibrium equations are: H-->p+e, H_2-->H+H, H_2-->H_2(+)+e. For this evaluation, we take into account: i) The magnetic coupling between traslational and internal states of atoms. ii) Changes in rotational-vibrational modes of molecules, induced by B. iii) The affection of the magnetic field over the Saha Eqution.
