Answer:The product is ACS reagent grade with an assay of at least 99.0%.
Answer:This configuration contains 250 g.
Answer:The formula is FeSO₄·7H₂O.
Iron(II) sulfate heptahydrate is supplied as an ACS-reagent-grade ferrous sulfate with an assay of at least 99.0%. This configuration contains 250 g as powder or crystals. The compound has the formula FeSO₄·7H₂O, molecular weight 278.01 g/mol, and CAS number 7782-63-0. It is used as an iron source, reducing reagent, catalyst precursor, and inorganic salt in analytical chemistry, synthesis, environmental studies, and general laboratory work. Defined ACS impurity limits make it suitable for controlled procedures where reagent purity is important. A 50 g/L aqueous solution is acidic, with a pH of approximately 3–4 at 25 °C.
