Sodium sulfide is a class of corrosive items, such items, whether we use or storage, should be extra careful, do a good job of basic protection. Recently, there are a lot of people wondering whether it has an explosive hazard? What do you think? Whether it is explosive or not, let us find the answer together.

Sodium sulfide at room temperature pure product is colorless or slightly purple prism crystal, industrial products because of impurities often pink, brown red, earth yellow block, itself is a certain odor, its solubility can be dissolved in cold water, very easy to dissolve in hot water, slightly soluble in alcohol. Industrial products are generally the mixture of different crystal water, and contain different degrees of impurities, in addition to the appearance of different color, density, melting point, boiling point, etc., are also different because of the influence of impurities.

In fact, sodium sulfide does not have some factors of flammability, but although it is not flammable, has a strong corrosive, irritating, can cause human burns. Is a very strong corrosion, when sodium sulfide combustion will produce some of the nature of pollution decomposition products: hydrogen sulfide, sulfur oxide, and it will meet acid decomposition, the release of highly toxic flammable gas. Its aqueous solution is corrosive and highly irritating. Evaporation begins at 100 ℃, and the vapor can erode the glass.

Through the above content, we know that sodium sulfide is not flammable, but its corrosion is really very strong, if accidentally contact with the skin, it will quickly burn people. When we use it, we should pay attention to our own protection.
