[@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.

It's in comment

[@rabiazaryab7884]

thank you

[@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.

[@imsaksham1]

Please share with your groups fast.

For Sulphur test - Thiourea
For Halogen test - Chlorobenzene

[@_ash_ish_]

Sir u added acetic acid in sulphur test but it was not mentioned in the reaction. Why?

[@imsaksham1]

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

[@_ash_ish_]

@@imsaksham1 but it(acetic acid)
has to be added during the procedure right?

And one more doubt
Is it necessary to do lassaigne test twice as you did in the video?

[@imsaksham1]

Yes

[@imsaksham1]

We have to take sodium metal twice for correct results. You can take it once also.

First of all its educational video for undergraduate science students. Some chemicals used in this experiment are hazardous and flamable. I am serious because I want every student listen it seriously and not as entertainment.

Ignition tube use for na fussion test,why we do not wash it ? Why we dont not use again any one tell me this reason???

I want this answer

[@imsaksham1]

I will answer this assuming you watch video till end.
As name suggests these are ingition tubes, if any contamination present then it will remove during ignition of tubes.
In this experiment, we break these tubes in distilled water, so no point to reuse it.
