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_(2)O)_(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_(4)[Fe(CN)_(6)]. Q. Anhydrous FeCl_(2) is made by :

Answer»

HEATING Fe with DILUTE HCl
