Zinc Nitrate Sodium Sulfide
The change between zinc nitrate and sodium sulfide
At some point, there are both zinc nitrate and sodium sulfide. Zinc nitrate is peaceful in nature, sitting in a bottle, colorless and transparent, like still water. Sodium sulfide is also on the side, its color is yellowish, with a slight odor, and exists in other utensils.
One day, I want to see the intersection of the two. Then take an appropriate amount of zinc nitrate solution, pour it into a dish, and absorb the sodium sulfide solution with a dropper, and slowly drop it into it. At first, the drop into the zinc nitrate solution is like a stone falling into a shallow pool, and at first it is slightly turbulent. Then, in the solution, it is gradually turbid, and something seems to come out of the hidden place.
After a while, the turbidity intensifies, and it turns into a milky white color, like morning mist condensing and suspended in the liquid. Upon closer inspection, there is a precipitation, which is dense and heavy, and slowly settles at the bottom of the dish.
Investigate the reason, zinc ions in zinc nitrate and sulfur ions in sodium sulfide touch, and the two agree and synthesize zinc sulfide precipitation. This is a chemical change, the material blends, and the properties change. Although silent and invisible, the changes are wonderful, revealing the secrets of nature, which cannot be solved by human force. Only by scientific methods can we understand.
