4Solubility. Slowly sol in water; rapidly sol in the presence of a trace of ferrous sulfate; sparingly sol in alc; practically insol in acetone, ethyl acetate.

How does FE change to Fe3+?

The electron configuration of Fe2+ is [Ar] 3d6. The next electron is removed from the 3d subshell. The electron configuration of Fe3+ is [Ar] 3d5.

How do you identify a precipitate?

The identity of the precipitate can often be determined by examining solubility rules. It also occurs in single displacement when one metal ion in solution is replaced by another metal ion. Notice the new solid forming on the bottom of the tube.

Quelle est la couleur de l’oxyde de fer?

Il est de couleur ocre à rouille sous forme pulvérulente — ce qui donne notamment sa couleur à la planète Mars — mais grise à noire sous forme cristallisée. Il est l’un des trois oxydes principaux du fer, les deux autres étant l’oxyde de fer(II) FeO, plutôt rare, et l’oxyde de fer(II,III) Fe3O4.

Qu’est-ce que le fer2o3?

β-Fe2O3 a une structure cubique à faces centrées. Il est métastable, et redonne la phase α au-dessus d’environ 500 °C. Il peut être produit par réduction de l’hématite au carbone, pyrolyse d’une solution de perchlorure de fer ou thermolyse de sulfate ferrique.
