Thank you Michel. Actually, I wanted to show how to prepare
Sodium thiosulfate but it was hard and time consuming. So, I
skipped that part. I kept dissolving sulfur in boiling sodium
sulfite solution. I've started off with 150ml solution,
stirring, stirring, stirring, and the solution was basic even
after it came to 20ml mark hahaha. So, skipped it. Well, it can
also be prepared by passing sulfur dioxide in Sodium sulfide
solution. But, I do not have Sodium sulfide and won't buy it
anyway as it will liberate smelly and very toxic hydrogen
sulfide on hydrolysis.

Great video. And well, your hands are too deft with the stuff...
I am used to spilling chemicals and breaking test tubes in my
school lab (mostly intentionally).
Can you add the photographic plate reaction with it too? I want
to see how it occurs (of course, if you have AgBr at your
disposal). Thanks a lot in advance. :)
