How do you balance this equation? #Fe(NO_3)_3 + KSCN -> Fe(NO_3)_3 + KSCN#
Since,the reactants side is the same as product side,hence, no chemical reaction has taken place.
Hence,since it isn't even a chemical reaction it cant be ballanced.
The tristhiocyanato iron species is a so-called complex ion. Both mass and charge are balanced in the equation.
You haven't actually written any products but I will describe the reaction below:
Iron(III) ions form a blood-red complex with thiocyanate ions in a 1:1 molar ratio.
The ionic equation which omits the spectator ions is:
The complex is very intensely coloured and this reaction is often used as a qualitative test for iron(III) ions.
Strictly speaking we have a ligand exchange reaction:
The reaction is shown here:
