Precipitation of nickel (II) acetate and ferrous chloride
At some point, there was a desire to study the mixing of nickel (II) acetate and ferrous chloride. The two come into contact with water in the vessel, and the ions swim together. Nickel ions, acetate ions, ferrous ions, and chloride ions are disturbed in the liquid.

Russia, or due to the nature of the solution and the affinity of ions, there is a gradual appearance of precipitation. Ferrous ions interact with acetate ions, or nickel ions and chloride ions, and gradually coalesce into particles. The particles increase, and then form a precipitation, which falls at the bottom of the vessel.

Everyone looked at it and observed the color and quality of the precipitation in detail. Either light green or light brown, depending on the reaction situation. If you want to investigate it clearly, or take the precipitation, use various methods to test it. If you burn it with fire, observe its change; if you test it with other agents, observe its response. Hope to know the structure and nature of this precipitation, for later research and preparation.
