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.

#Fe(NO_3)_3 + 3KSCN rarr [Fe(SCN)_3] + 3KNO_3#


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.

#Fe(NO_3)_3# + #KSCNrarr[FeSCN]^(2+)+K^++3NO_3^-#

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:
