Cadmium II Chloride Sodium Sulfide

The Reaction of Cadmium (ⅱ) Chloride and Sodium Sulfide
Over the years, there have been scholars who have learned to study the wonders of material change. One day, I obtained both cadmium (ⅱ) chloride and sodium sulfide, in order to explore the change of their encounter.

Cadmium (ⅱ) chloride, white in color and pure in quality, dissolves in water, and becomes a clear liquid. It is quiet in view, as if nothing had changed. Sodium sulfide is also soluble in water, and its liquid is slightly yellowish and has a specific taste.

When the liquid of sodium sulfide is gradually injected into the liquid of cadmium (ⅱ) chloride, there is a strange phenomenon in Russia. However, in the solution, the precipitation slowly accumulated, and its color was brown and yellow, like dust at the beginning, gradually condensed and settled at the bottom of the vessel. This precipitator is a new product produced by the combination of the two.

Looking at this change, it is really a wonder of chemistry. Cadmium (ⅱ) ions and chloride ions are accompanied in front, and when they encounter sulfur ions and sodium ions in sodium sulfide, they then combine. The state of the ions changes, and new substances are formed. This mechanism is in line with the common sense of material changes. Yin and yang are combined, and the combination is regular. Here, scholars can get a glimpse of one of the reactions of matter, and they can also understand the mystery of chemical changes, which can be used to delve deeper into the foundation in the future.
