Hi Guys so i just got the MSDS for a product i would like to use but want to make sure it's safe to use in extractions as the acid, i was pretty certain it would be ok but want to be sure.

Here below is a copy of the (Composition/Information on Ingredients) that i copied from the MSDS:

Composition/Information on Ingredients





Ingredients:-------|------CAS:------------|------|------Proportion:

Ferrous Sulphate------|------7720-78-7-------|------|-----<10 %

Can anyone tell me if this is ok to use?
