## Questions & Answers

**Q: why does this say 20 percent iron? is it still 100% FeSO4?**
A: The molar mass of the compound (ferrous sulfate hepthydrate) is about 278 g/mol.  The molar mass of iron is about 56.  56/278 = 20% iron and 80% everything else.

**Q: Is this the same ingredients  as copperas**
A: Ignore the other guy. Copperas = Iron sulfate

**Q: Is this product good for acidifying soil for blueberries?**
A: There are better products. Some iron (within reason) helps green up most plants, but the ferrous iron is a reductant, more like a weak base (sorta) than an acid. To acidify, use (dilute!) sulfuric or phosphoric acid, mono- or dibasic potassium phosphate, or elemental sulfur.

**Q: will this product control moss in a flower garden without significantly affecting the PH of the soil?**
A: no. this will lower the pH slightly. also i think you are referring to algae, which grows as a result of compaction and too much water.
