If it can be extremely complex to understand, chemistry offers a rather fantastic show to anyone who wants to watch. We offer regular photos and videos all the more impressive as each other. This time it is a nice little chemistry phenol magic trick.
You know the 4-hydroxybenzaldehyde? phenol Me neither! According to Wikipedia, phenol it is a phenolic aldehyde, one of the three isomers of hydroxybenzaldehyde. In particular it is found in Gastrodia elata Orchid.
Nothing folichon frankly, for sure! But if we plunge a hot aqueous solution phenol of impure 4-hydroxybenzaldehyde in ice water, the compound begins to crystallize. This is the magnetic stirrer causes these swirling motions. After a few seconds the 4-hydroxybenzaldehyde changes color and consistency. Pretty nice, right?
