Unknown #1 - Identification of Unknowns (Lab Practical) — Transcript

Full transcript

1. 0:10hello chemistry students today we will
2. 0:12be continuing the identification of
3. 0:13unknowns experiment
4. 0:15by identifying an unknown organic
5. 0:17compound
6. 0:18you will need to observe the color and
7. 0:20physical state of the compound
8. 0:22determine the melting or boiling point
9. 0:24analyze its solubility behavior
10. 0:26use selective chemical classification
11. 0:28tests which we have previously reviewed
12. 0:31and analyzed the infrared spectrum in
13. 0:33order to determine the identity of the
14. 0:35unknown compound
15. 0:37from the following list
16. 0:49let's get started you will need to
17. 0:51determine the identity of
18. 0:53unknown compound number one and this is
19. 0:56what
20. 0:56unknown number one looks like we will
21. 0:59now perform a melting point
22. 1:01determination of
23. 1:02unknown number one
24. 1:50we will now perform a solubility test
25. 1:52for unknown number one
26. 2:37we will now perform an unsaturation test
27. 2:40for unknown number one
28. 3:01we will next check the ph of an aqueous
29. 3:03solution
30. 3:04in which unknown number one has been
31. 3:16dissolved
32. 3:40we will next dissolve a small amount of
33. 3:42unknown number one
34. 3:44in a five percent aqueous sodium
35. 3:46bicarbonate solution and observe the
36. 3:48solution carefully
37. 4:17okay students you should now have enough
38. 4:19information to determine the identity of
39. 4:21the unknown organic compound
40. 4:23this concludes the identification of
41. 4:25unknown's experiment
42. 4:26thank you for joining me for this
