What Is The Solubility Of Sodium Sulfide?

The solubility of sodium sulfide (Na2S) depends on a few factors, such as temperature and the presence of other chemicals in the solution. At room temperature, sodium sulfide is soluble in water to a certain extent, with a maximum solubility of about 14 g/100 mL. However, as the temperature increases, the solubility of Na2S in water also increases significantly.

It should be noted that the solubility of Na2S can also be affected by the pH of the solution. In acidic conditions, Na2S will react with H+ ions to form hydrogen sulfide gas (H2S), which is not soluble in water. On the other hand, in strongly basic solutions, Na2S may undergo hydrolysis to produce sodium hydroxide (NaOH) and hydrogen sulfide gas.

In summary, the solubility of sodium sulfide is dependent on various factors, including temperature, pH, and the presence of other chemicals in the solution.
