The acdicaqueoussolutionof ferrous ionforms a browncomplex in thepresence of NO_(3)^(Θ)by thefollowingtwosteps [Fe(H_(2)O)_(6)]^(2+) + NO_(3)^(Theta) + H^(o+)rarr ….+ [Fe(H_(2)O)_(6)]^(3+) + H_(2)O[Fe(H_(2)O)_(6)]^(3+) + ..... rarr ....+ H_(2)O Complex andbalance the equations.

Answer»

Solution :`3[Fe(H_(2)O)_(6)]^(2+) +NO_(3)^(Theta) +4H^(o+) RARR NO +3 [Fe(H_(2)O)_(6)]^(3+) +2H_(2)O`
`[Fe(H_(2)O)_(6)]^(2+) +NO rarr [Fe(H_(2)O)_(5)NO]^(2+) +H_(2)O`
