Ferrous Sulphate

Ferrous Sulphate Hexahydrate (Crystals)

We are manufacturing Ferrous Sulphate Hexahydrate in Technical, Pure & LR Grade.
These Products are available in 50 kgs Bag/Drum.

This product is much less affected by oxygen in the air than iron sulfate, making it more desirable for titration purposes, where iron might be oxidized to iron. The oxidation of iron to iron is pH dependent, and the reaction occurs more rapidly at higher pH; Mohr’s Salt lowers the pH of solutions slightly.
