Iron (+II) is one of the most important oxidation states, and salts are called ferrous salts. Most of the Fe (+II) salts are pale green and contain [Fe(H_2O)_6]^(2+) ion. Fe (+II) compounds are easily oxidised by air. and so are difficult to obtain pure Fe^(2+) form many complexes like K_3[Fe(CN)_6] Anhydrous FeCl_2 is made by
