Sodium Sulfide Zinc Nitrate Precipitate
Sodium Sulfide and Zinc Nitrate Precipitation
At some point, there is a desire to test the mixing of Sodium Sulfide and Zinc Nitrate. Then take the liquid of sodium sulfide and pour it into the container containing zinc nitrate.
At the beginning, the liquid was still clear, and after a while, the color gradually changed, and it seemed to have life. Suddenly, it is slightly muddy and gradually appears, like a fog rising from the abyss. After a while, the precipitation appears, the color is black or brown, and it sinks at the bottom of the vessel.
Looking at this precipitation, think about why. Sulfur ions in the cover of sodium sulfide, zinc ions in zinc nitrate, the two are combined, making it insoluble, so it sinks. The wonder of this change cannot be known without careful inspection, nor can it be understood without deep thought. After the test, I would like to record its image for later examination.
