CuSO4 & KCl ๐Ÿ”ฌ ๐Ÿ’Ž โš—๏ธ

A pleasant succession of crystal shapes. The star-shaped ones can hardly be discerned at the end.

What else do we see? ๐Ÿ”ฌ

RuCl3 & NaCl in evaporating H2O ๐Ÿ’Ž ๐Ÿ”ฌ โš—๏ธ

Fairly small quantities of RuCl3 can produce pitch black aqueous solutions, from which we gradually see crystals of NaCl emerge here.

Rhodium (iii) chloride is a deliquescent substance that forms red aqueous solutions. It is here combined with NaCl. One of the stable phases we may thus afford is Na3RhCl6.

โš—๏ธ cyanotype โš—๏ธ chemistry โš—๏ธ
In cyanotype, we employ K4Fe(CN)6 and a light-sensitive source of Fe(III), to displace K+ and form insoluble prussian blue. Here instead I added an excess of FeCl3โ€ข7H2O as a moisture-sensitive source of Fe(III). Dark shades of green and blue indeed develop initially, but we then proceed to form something else.

MnCl2โ€ข5H2O ๐Ÿ’Ž in HgCl2(aq). After two days of dissolution and growth due to humidity variations, we're now gradually seeing very neat crystal shapes that develop.

๐Ÿ’Žโš—๏ธ๐Ÿงช๐Ÿงซ๐ŸŒง๏ธ Deliquescent HgCl2 picks up moisture to form a solution. Some CoCl2โ€ข6H2O also enters and now the moisture content is directly reflected in the color of the solution.
This was filmed on a rainy day with some dry periods, and we see periods of crystal growth (โ›…) and periods of crystal dissolution (๐ŸŒง๏ธ) , remodeling the shape of the grains ๐Ÿ’Ž.

CuCl2 & LiCl โš—๏ธ ๐Ÿงช ๐Ÿ’Ž ๐Ÿ”ฌ
anhydrous CuCl2 is a brown substance, which progressively turns green (and then blue) upon pickup of moisture. The CuCl2 we start with here has already developed quite a few green patches and is clearly not as dry as it could have been. Upon addition of highly deliquescent LiCl, we soon recover a brown color. 1/2
