Lassaigne's Test I Sodium Fusion Extract I Nitrogen, Sulphur, Halogen I 50K Views

This video explains a detailed experiment with related theory. Nitrogen, sulfur, and halogens are identified in the laboratory through Lassaigne's test. The first step is to prepare a sodium fusion extract using sodium metal. Sodium metal reacts with nitrogen, sulfur, or halogens (depending on the element present) and is converted to corresponding inorganic compounds (detailed reactions are given in the video).

[@Islamic_insights.official786]

excellent job sir
I'm confused while making sodium fusion extract, how can we know which organic compounds have to take and does that organic compound has an effect on the elements that are determining?

[@imsaksham1]

I don't understood your question fully. You can select organic compound randomly and perform the test.

[@thara0007]

Is it okay that fusion tube melts in the water?

Fusion tube breaks in water as it is very hot

[@monikaaswal7914]

why we choose only sodium metal for element detection ?? Please reply Fast

[@imsaksham1]

Sodium metal reacts easily with organic compound as compared to other metals. It will react to form easily detectable inorganic compounds. We can store it in kerosese and can cut easily into small pieces. Most important it's cheap.

Acetic acid create common ion effect here. Black colour ppt is of lead sulphide so no direct involvement of acetic acid.
