   ferrous sulfate

Ferrous sulfate is blue-green monoclinic crystal or particle, no smell. It is weathered in dry air and oxidized to brown basic ferric sulfate in moist air. It becomes tetrahydrate at 56.6 ℃ and monohydrate at 65 ℃. Soluble in water, almost insoluble in ethanol. Its aqueous solution oxidizes slowly in air when it is cold and fast when it is hot. The addition of alkali or light can accelerate the oxidation. The relative density (D15) was 1.897. It's irritating. Anhydrous ferrous sulfate is a white powder, containing crystal water is a light green crystal, commonly known as "alum", dissolved in water solution is light green.

5. Agriculture

Regulating soil pH and promoting the formation of chlorophyll (also known as iron fertilizer) can prevent and control the yellow disease of flowers and trees caused by iron deficiency. It is an indispensable element of acid flowers and trees, especially iron trees.

It can also be used as fertilizer to control apple scab and scab on fruit trees.
 

6. Analytical Chemistry

Ferrous sulfate can be used as a chromatographic reagent.
 

   Operation precautions:

Local airtight ventilation, 1.

2. Prevent dust from being released into the air of the workshop. Operators must be specially trained and strictly abide by the operation rules.

3. It is suggested that operators should wear self-priming filter dust masks, chemical safety glasses, rubber acid and alkali resistant clothes and rubber acid and alkali resistant gloves.

4. Avoid dust.

5. Avoid contact with oxidant and alkali.

6. Equipped with leakage emergency treatment equipment. The empty container may contain harmful substances.
 

   Storage precautions:

1. Store in a cool and ventilated warehouse.

2. Keep away from fire and heat source.

3. Prevent direct sunlight.

4. The package must be sealed, and do not get damp.

5. It should be stored separately from oxidant and alkali, and mixed storage is not allowed.

6. The storage area should be equipped with suitable materials to hold the leakage.
