Iron may be present in the rainwater in the form of Ferrous Sulphate, Ferric Sulphate, Ferrous Nitrate or Ferric Nitrate. But as per the procedure of lab standards we will check the concentration of Iron i.e., Fe. How do I know whether it is Fe2+ or Fe3+ ion.

1. You should read the FAQ and forum guidelines. What procedure of lab standards are you using? This will help determine recommendations. Citations are generally required for posts outside of Beginnings.

2. Is this work or school? This is a hobby forum and your post sounds like work to me. If you want a theoretical answer, I would probably look into XRD, XANES, Mossbauer, or a similar spectroscopic technique. Alternatively, properly separated components might be subjected to coulometry and the mass per charge reduction calculated, but I doubt the fidelity of this is very accurate. What is appropriate for you is obviously not determinable from the extreme vagueness of your post.

It is for research work
