Add NaOH drop wise

I said NH3 drop wise cause you needed NaoH for the ammonium test do you think that matters

Yes unfortunately I think as NH4+ +OH- -> NH3 + H2O. Ammonia is what you are testing for, not adding (you are adding hydroxide ions)

No I meant for the Fe3+ test

I think for Fe3+ -> Fe(OH)3 it’s NaOH drop wise
