Fe2(CO3)3 Carbonate has an oxidation number of -2, iron (III) has an oxidation state of +3. Iron Iii Carbonate. Fe2(CO3)3. Fe2(CO3)3 is correct. Fe(CO3)3. ferrous carbonate (â²ferÂ·És â²kÃ¤rÂ·bÉâ²nÄt) (inorganic chemistry) FeCO3 Green rhombohedral crystals that are soluble in carbonated water and decompose when heated; used in medicine.
And carbonate anion also has the valency two. So the formula ZnCO3. In ionic forms Zn2+ and CO32-. Zinc carbonate is formed by the reaction with zinc hydroxide or Zinc metal with carbonic acide. Carbonic acid is nothing but carbon di oxide gas dissolved in water. (Soft drink beverages) Zn + H2CO3 = ZnCO3 + H2 Zinc carbonate is different from zinc bi carbonate Zn(HCO3)2 By Dr M Kanagasabapathy Asst.
