After dissolving the unknown solid 38 in distilled water‚ we heated the solution. We then added Norit charcoal‚ a substance added to solutions in order to remove impurities because it is able to absorb a large range of contaminants‚ until the solution was a light green color. Next‚ we used hot gravity filtration to filter the charcoal out. After doing this‚ we allowed the solution to cool to room temperature before placing it in an ice bath to form crystals. About
