SodiumSulfideAndIronIIChloridePrecipitate
Nowadays, sodium sulfide ($Na_2S $) and ferrous chloride ($FeCl_2 $) are mixed, resulting in precipitation.
Sodium sulfide is soluble in water and alkaline, and sulfur ions ($S ^ {2 -} $) have strong reductive properties. Ferrous chloride is also soluble in water, and ferrous ions ($Fe ^ {2 +} $) have certain reductive and oxidative properties.
When the two solutions are mixed, sulfur ions interact with ferrous ions and react: $Na_2S + FeCl_2 = FeS? + 2NaCl $. The resulting ferrous sulfide ($FeS $) is a black precipitate and is insoluble in water. This is due to the small solubility product constant of ferrous sulfide. In solution, when the concentration of ferrous ions and sulfur ions exceeds the solubility product of ferrous sulfide, precipitation will be precipitated.
Looking at this reaction, following the law of metathesis reaction, anions and cations exchange components with each other to form insoluble ferrous sulfide and soluble sodium chloride. This reaction is commonly used in chemical experiments and chemical production, and can be used to prepare ferrous sulfide. It can also be used to remove ferrous ions or sulfur ions from the solution to purify the solution.
