Iron(II)sulfate (T) is a substance for experimentation for education, development, research and hobby.


Iron(II)sulfate can be used, among other things, for experiments with precipitates and redox reactions. Certain inks are made with iron sulfate. Note: occasionally the brown iron(III)sulfate is needed for these inks! When dyeing wool and silk, it can be used as a mordant, for fixing the dye in the fibres. Besides that, it is used as a moss-killing agent in lawns.


We sell the hydrous iron(II)sulfate hepta hydrate. This contains a certain amount of iron(III)sulfate, which is brown in color. Over time, the color of the substance changes more and more from green to brown. Almost always there are brown pieces / brown speckles in it. To counteract this, a small amount of sulfuric acid has been added. Iron sulfate has been used by people for centuries. In some places this can be mined in a fairly pure form as "iron vitriol". Today it is made from waste from the steel industry or from pure iron and sulfuric acid.


Iron(II) sulfate is classified as hazardous (REACH/CLP), with the following designations: WARNING H302 - Harmful if swallowed. H315 - Causes skin irritation. H319 - Causes serious eye irritation.
