WebWhat is the structure of $\ce{FeSO4 \cdot NO}$ that is formed when $\ce{NO}$ is passed through ferrous sulphate solution? The structure is octahedral. The Fe ion is at the center of the octahedron. Five water molecules and the NO molecule occupy the vertices of the octahedron. Sulfate is a separate spectator ion. WebFerrous sulphate BP, FeSO4,7H2O, dehydrates to form FeSO4,4H2O when the relative humidity (RH) is less than 65%, or on heating at 40 degrees C. The tetrahydrate was also prepared by recrystallization at 60 degrees C from aqeuous solutions of the sulphate. Commercial dried ferrous sulphate BP is FeSO … WebThe frequency of light absorbed is proportional to the excitation energy. This frequency is usually in the visible range.
