Precipitation reactions in nature can account for mineral formation in many cases, such as with undersea vents called black smokers that form metal sulfides. In a common dry cell and in alkaline batteries, two electrons per zinc atom are transferred to the oxidizing agent, thereby converting zinc metal to the Zn2+ ion. around the world. . To determine whether a precipitation reaction will occur, we identify each species in the solution and then refer to Table \(\PageIndex{1}\) to see which, if any, combination(s) of cation and anion are likely to produce an insoluble salt. CaS is produced by "carbothermic reduction" of calcium sulfate, which entails the conversion of carbon, usually as charcoal, to carbon dioxide: In the second reaction the sulfate (+6 oxidation state) oxidizes the sulfide (-2 oxidation state) to sulfur dioxide (+4 oxidation state), while it is being reduced to sulfur dioxide itself (+4 oxidation state).
