Wildlife volunteering is a broad topic and there really is something for everyone. Some projects involve really getting your hands dirty in the jungle, but if this does not sound like your thing there are also plenty of other ways to get involved.
EXPERIMENT 2: Recrystallization and Melting Point. Melting Point is: â¢a constant physical property of a solid (the temperature at which it turns to a liquid) â¢reported in the lab as a melting point range (usually 1â2 ËC wide), not as a single temperature.
Dissolve 0.1 to 1 mg of the sample in 0.1 mL solvent, add. 0.1 mL of the respective anhydride and heat to 60â70 Â°C for. 1â2 hours. If the sample need not be concentrated prior to. the analysis and if there is no danger of catalytically induced. side reactions, pyridine is used as solvent.
