Question

the ionic compound feco₃ is the primary component of the orange mineral siderite. what is its name? refer to a periodic table and a list of polyatomic ions. its name is

Explanation:

• For ionic compounds, the name is formed by naming the cation first and then the anion.
• The cation here is Fe (iron). Iron can have multiple oxidation states. In \(FeCO_3\), the carbonate ion (\(CO_3^{2 -}\)) has a charge of - 2. For the compound to be neutral, the iron ion must have a charge of + 2. So the cation is iron(II) ion.
• The anion \(CO_3^{2 -}\) is called carbonate ion.

Answer:

Iron(II) carbonate
