Let us assume that Fe(OH)₃(s)Fe(OH)₃(s) is completely insoluble, which signifies that the precipitation reaction with NaOH(aq)NaOH(aq) (presented in the transition) would go to completion.
Fe₃+(aq)+3NaOH(aq) → Fe(OH)₃(s)+3Na+(aq)Fe₃+(aq)+3NaOH(aq) → Fe(OH)₃(s)+3Na+(aq)
If you had a 0.450 LL solution containing 0.0150 MM of Fe₃+(aq)Fe₃+(aq), and you wished to add enough 1.28 MM NaOH(aq) NaOH(aq) to precipitate all of the metal,
what is the minimum amount of the NaOH(aq)NaOH(aq) solution you would need to add?
Assume that the NaOH(aq)NaOH(aq) solution is the only source of OH−(aq)OH−(aq) for the precipitation.
