Potassium selenide is mainly used in chemical research and industrial synthesis, but due to its toxicity, strict safety measures need to be taken when using it.

The reaction of potassium selenide (K ₂ Se) in water is mainly a hydrolysis reaction. It reacts with water to generate hydrogen selenide (H ₂ Se) and potassium hydroxide (KOH). This reaction produces hydrogen selenide gas, which has strong toxicity and irritating odor. Therefore, when operating in the laboratory, it must be carried out in a well ventilated area and necessary safety measures must be taken. In addition, potassium selenide also reacts with acids to generate hydrogen selenide. The generated hydrogen selenide gas can further undergo combustion reaction with oxygen to produce selenium and water. In summary, the reaction process of potassium selenide involves multiple steps and chemical changes, and each step requires careful operation and control to ensure safety.
