What is Ferrous sulfate
Ferrous sulfate is an inorganic substance with the chemical formula FeSO4. It appears as a white powder and is odorless. Its crystalline hydrate is heptahydrate at room temperature, commonly known as “green vitriol”. It is light green crystal. Becomes tetrahydrate at 56.6°C. , changes to monohydrate at 65°C. Easily soluble in water, almost insoluble in ethanol. Its aqueous solution oxidizes slowly in the air when it is cold and quickly when it is hot. Adding alkali or being exposed to light can accelerate its oxidation. Relative density (d15) 1.897. Annoying.

It is an indispensable element for acid-loving flowers and trees, especially iron trees. In agriculture, it can also be used as a pesticide to prevent and control wheat smut, apple and pear scab, and fruit tree rot; it can also be used as a fertilizer to remove moss and lichen on tree trunks.
Analytical Chemistry Colorants
It can be used as a chromatographic analysis reagent.
