Chrome iron ore (x) was heated with dry Na_(2)CO_(3) in the presence of quick lime and air in a furnace. The mixture was extracted with water and filtered. The filtrate was yellow(A) which on adding conc. H_(2)SO_(4) turned to orange red. The solution was evaporated and cooled. The crystals of B were obtained. To the crystals in aqueous solution, NH_(4)Cl was added. On fractional crystallization, orange red crystals (C ) is formed. B was obtained by fractional crystallization. The compound crystallized first was
