    STATEMENT - 1 : Fe^(+3) gives brown coloured ppt with K_(3)[FeCN)_(6)]. and STATEMENT - 2 : Formation of undissociated complex Fe[Fe(CN)_(6)] take place.

    The hybridization states of the central atom in the complexes [Fe(CN)_(6)]^(3-),[Fe(CN)_(6)]^(4-) and [Co(NO_(2))_(6)]^(3-) are:

    The complex Na_(2)[Fe(CN)_(5)NO] is called :

    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. K_(3)[Fe(CN)_(6)] is used in the detection of Fe^(2+) ion with which it gives a deep blue colour. This colour is due to the formation of :
