What is feco3?

Feco3 is the chemical formula for iron(II) carbonate, a chemical compound that is a pale green powder. It is insoluble in water and is often used in chemical reactions and as a pigment in paint and ceramics. Iron(II) carbonate can be synthesized by reacting iron(II) chloride with sodium bicarbonate. It has a molar mass of 115.85 g/mol and a melting point of 1400°C. Iron(II) carbonate is not commonly found in nature, but it can be formed through the weathering of iron-containing minerals.
