Sodium Sulfide Acid or Base
Whether sodium sulfide is an acid or a base is an interesting question in chemistry. When sodium sulfide dissolves in water, a hydrolysis reaction occurs. The hydrolysis process is quite complicated. Sulfur ions ($S ^ {2 -} $) interact with water molecules and combine hydrogen ions ($H ^{+}$）， in water to promote a positive shift in the ionization balance of water, resulting in an increase in the concentration of hydroxide ions ($OH ^ {-} $) in the solution.
Therefore, the aqueous solution of sodium sulfide is alkaline. The principle behind this phenomenon is closely related to the law of salt hydrolysis. Many similar salts exhibit specific acidity and alkalinity in water due to the interaction between ions and water molecules. The chemical principles contained in this have crucial applications in chemical production, water quality treatment and many other fields. Knowing the nature of the acidity and alkalinity of sodium sulfide and other substances can make better use of its characteristics and serve practical production and life.
