What is the alternative use of H2S gas in Lab. and why?
Ans: H2S gas is used in Lab. for semi-micro analysis. Continuously H2S gas is supplied in a lab. by Kip apparatus.
This gas is poisonous and malodor. It creates a headache, nausea, inconvenience environment. So to solve this problem we can use thioacetamide(CH3-CS-NH2). It is dissolved in hot water to produce H2S gas.
CH3-CS-NH2 + H2O ----> CH3-CO-NH2 + H2S
Produced H2S gas react with the element of a solution and dismissed. Due to the slow reaction rate of producing H2S gas, it can
not come o environment. That is why no problem is created.
