In summary, ferrous sulfate comes in two forms: wet and dried. The wet version has 65mg of elemental iron per 325 mg tablet, while the dried version has 50 mg per 160 mg tablet. This difference in amounts suggests that the wet version contains water. The common form of Ferrous Sulphate is the heptahydrate version with a molecular weight of about 276, containing 20% Fe. The anhydrous form has a molecular weight of about 150 and contains 37% Fe. This explains why the percentages in the dried version match the chemical formula better. However, it appears that the tablet is not entirely made of anhydrous ferrous sulfate. Overall, the

I have read that ferrous sulfate has 65mg of elemental iron per 325 mg tablet. Then I read that dried ferrous sulfate has 50 mg per 160 mg tablet. Does this mean that the wet ferrous sulfate has water with it? It seems that the dried version matches the percentages based on the chemical formula.

I think the common form of Ferrous Sulphate is the heptahydrate with a molecular weight of about 276, containing 20% Fe
The anhydrous form would have a molecular weight of about 150 and contain 37% Fe. (Which would suggest the tablet is not all anhydrous ferrous sulphate.)

This makes sense. Thanks

Oh - just noticed, I can't add up! The MW for anhydrous ferrous sulphate is nearer 152 and the heptahydrate 278, but it's near enough to keep the rounded %s the same.

I noticed that. I figured we were using a different version of the periodic table :-)
 

Related to Elemental iron in ferrous sulfate

1. What is elemental iron in ferrous sulfate?

Elemental iron in ferrous sulfate is a type of iron supplement that contains a form of iron called ferrous sulfate. Ferrous sulfate is a compound made up of iron and sulfur that is commonly used to treat iron deficiency anemia.

2. How does elemental iron in ferrous sulfate work?

Elemental iron in ferrous sulfate works by providing the body with additional iron, which is necessary for the production of red blood cells. Red blood cells carry oxygen throughout the body, and a deficiency in iron can lead to anemia and other health problems.
