Sodium Sulfide Iron III Chloride
A certain person wants to know about the phase combination of sodium sulfide and ferric chloride (Sodium Sulfide, Iron III Chloride). It is to take the sodium sulfide solution and drop a little in the container containing the ferric chloride solution. Seeing its color change, there is precipitation. At first, the ferric chloride solution is yellow-brown in color, and the sodium sulfide solution is colorless. Mixing the two, the gradual black precipitation occurs, and the color of the solution also changes. The sulfur ion in the cover sulfide and the iron ion in the ferric chloride combine to form a precipitation of iron sulfide. The reason why it should be is because of the ionization phase. When the two meet, the sulfur ion is reductive, and the iron ion is oxidizing, so it is redox. Sulfur ions lose electrons, iron ions gain electrons, change their valence states, and eventually form iron sulfide and other substances. Sheng carefully observes its changes, remembers its images, and thinks rationally. In the way of chemistry, it is another point.
