Iron II Nitrate Sodium Sulfide Precipitate
Precipitation reaction of iron (II) nitrate and sodium sulfide
into the iron (II) nitrate solution, slowly dripping into the sodium sulfide solution. In an instant, there seems to be an undercurrent in the solution, and the originally clear iron (II) nitrate solution undergoes wonderful changes when it fuses with the sodium sulfide solution.
A black precipitate is rapidly formed in the solution. This is because iron (II) ions and sulfur ions attract each other and combine tightly to form a ferrous sulfide precipitate. The chemical equation of the reaction is: $Fe (NO_ {3}) _ {2} + Na_ {2} S = FeS? + 2NaNO_ {3} $.
The ferrous sulfide precipitate is black and heavy, and gradually settles at the bottom of the container. Its shape is like night falling, and darkness slowly gathers. The formation of this precipitate clearly shows that the chemical reaction of iron (II) nitrate and sodium sulfide occurs to form a water-insoluble ferrous sulfide, which precipitates from the solution system and appears in the form of precipitation.
