For Expt. #5 - iron (III) chloride and sodium hydroxide, if a reaction occurred here, what is the formula of the reactant anion?
Make sure to have the formula correct, then leave a space and have the charge. Do not try to use subscripts or superscripts. Do not include the state. For example: CrO4 2- or CrO4 -2 (for chromate ions) or NH4 + (for ammonium ions).
If there is no NIE, then write no NIE and nothing else.
