Hydroxide Precipitation Methods of Metals In An Insoluble Form

The FeS is precipitated by reacting solutions of an iron salt such as ferric chloride (FeCl 3) or ferrous sulfate (FeSO 4) with sodium sulfide (Na 2 S) or sodium hydrogen sulfide (NaHS), with the addition of an alkaline such as sodium hydroxide (NaOH) to raise the pH above 7 to prevent evolution of hydrogen sulfide (H 2 S) gas. It can also be ...
