In the “salting out” experiment, a water-soluble ionic salt is added to a mixture of water and a water-soluble organic liquid. While neither Grazyna nor Alfredo figured out exactly how I pulled off this trick, they both determined that I was making use of the “salting out” phenomenon. If you wish to know more about this challenge, please be sure to read the Challenge section found at the end of this blog post.Ĭongratulations to Grazyna Zreda and Alfredo Tifi who both solved Chemical Mystery #8. Preface: I am proposing a challenge based on this mystery.
