What is the complete ionic equation for NaOH(aq) + Fe(NO3)3(aq)?
I'm putting this on webassign, but it's telling me "One or more of your reactants appear to have an improper oxidation state. One or more of your products contains an improper oxidation state.
3Na^+ (aq) + 3OH^- (aq) + Fe^3+(aq) + 3NO^3- (aq) --> 3Na^+(aq) + 3NO^3-(aq) + Fe(OH)_3(s)
Hmmm. Looks good to me.
Sure your syntax is right? Do the spaces before (aq) and (s) matter?
It could be that _3 for Fe(OH)_3.
Most write it as Fe(OH)3
I'm not sure what I'm doing wrong it still says oxidation state is improper and no the spaces do not matter
I suspect the problem is the nitrate ion, NO3^-. You have written it as NO^3- on both sides. Write it as NO3^- on both sides.
To write the complete ionic equation for the reaction between NaOH(aq) and Fe(NO3)3(aq), we need to consider the dissociation of the compounds.
NaOH(aq) is a strong base and dissociates completely in water:
NaOH(aq) → Na+(aq) + OH-(aq)
Fe(NO3)3(aq) is a salt and dissociates into its constituent ions:
Fe(NO3)3(aq) → Fe3+(aq) + 3NO3-(aq)
Now, we can write the complete ionic equation by combining the dissociated ions:
3Na+(aq) + 3OH-(aq) + Fe3+(aq) + 3NO3-(aq) → 3Na+(aq) + 3NO3-(aq) + Fe(OH)3(s)
The equation is now balanced with the proper oxidation states for each of the ions involved.
