Thank you so much. I had a hard time visualizing the melting point technique when I read those steps in the O-Chem Lab Survival Manual. This video should be required viewing for new students since O-Chem labs cannot be done simply by reading about it.
Awesome video, the hardest part is definitely identifying the start of the melting range. You need to observe an actual drop, not just the substance moving away from the sides of the capillary.
Plz let me confirm that the glass capillary hole is open from just only 1 side or from both sides? Before jolting the capilary tube in the long glass tube.
+Enida Nushi If the sample is loose it will melt unevenly. Also he mentioned near the end that air is a thermal insulator, so you want to sample compact to get a narrow melting point.
I think because the more you have, the longer it takes to reach thermal equilibrium. (Think about if you put twice ad much food in a microwave, it takes longer)
This guy is rad! I absolutely wish I'd had him as my OChem lab instructor 10 years ago!

I am very happy that Dr. Davison took the time to make this video. Now I have an idea of what melting point is all about. Thank you again
Thanks for uploading this video... Now I actually have an idea of what I'll be doing in Lab!
"bounce bounce bounce" made me LOL
This was so helpful. I have been reading about the experiment and i have being so confused but just watching this has given me more insight.

Great professor!
Thank you for making this video! This was explained very well and useful as a refresher! :)
nice explanation...really helpful for chemistry students
Excellent video.
This is VERRRY HELPFULL
Gazakom Allah Khyran
This guy is great!
very helpful video
Anyone 2021?

Ke sini buat tugas kuliah 🐦
Finally I understand my lab lesson ,great video,but i have a question...Is there any good explanation of why do we pack the sample?

What’s the name of the rounded glass trays
Why does more substance take longer to melt than less substance?

Very awkward professor.
Awkward or not, hes got some great videos that are very informative and detailed.
@@jhyland87 nah you're just awkward
@@norman9052 i won't argue with you on that point :-P
