2023-09-14 07:54:58 +0000 UTCI’d say the only point I could raise is that it gives the false impression that you need a kiln to perform the reaction, which is not true, since heating for, say, 15 min with a blowtorch is enough to get a similar yield. Heating at 400°C for several hours is not something every amateur chemist can do (I, for example, don’t even have one of those portable kilns, so I’d probably feel stumped at that point). I suggest you insist in the final video on alternative, slightly more ‘OTC’ ways to get the reaction to work. That being said, great work as usual, and thanks again for your ongoing commitment to the making of didactical videos, unlike another big name of Youtube chemistry. PS – References: G. Pass, H. Sutcliffe: Practical Inorganic Chemistry (1974), p. 54; H.F. Walton, Inorganic Preparations – A Laboratory Manual (1948), pp. 150 et seq.

2023-09-14 05:40:14 +0000 UTCI love these "Lab Notes" videos. Reminds me of the sodium experiments. Great content as always!

2023-09-14 00:55:28 +0000 UTCinteresting idea! Is there any literature or papers i could look up? At first glance i think the reaction would produce manganese dioxide and precipitate out. And i've actually made manganese dioxide as an experiment this way once, so to push it to permanganate must require some specific conditions.

2023-09-13 21:34:56 +0000 UTCHow about making permanganate by Mn2+ oxidation with persulfate? Maybe using a tiny amount of silver salt as catalyst. I heard of qualitative reaction for Mn2+ this way (and quantitative using colorimetry).
