I find powerpoint much easier to use than other animation software. It is certainly more limited but I've been able to do most of what I want to get the point across (I hope). I have tried other animation software, and have found powerpoint simpler (=faster), but that could simply be because I don't have the patience to really learn some of the better ones out there. (!)
If you cool the solute and no crystallization occurs until then why when you do recrystallizations and you heat the solution then let it cool to room temperature it recrystallizes? I have done this in organic chemistry, could it be because not everything was fully dissolved? Great video!
While I use the same solutions year after year for my students' labs, which usually work fine, once in a while I encounter this problem. It is possible you are not heating it enough, but also there may be contaminants that have been introduced into the solution that act as seed crystals. When I see this issue and look closely, I always see a small contaminant in the solution.
Hello, I have a quick question. Many videos say anything above the solubility curve is supersaturated. However, my professor is telling us, as you say in the video, that over the curve, the solution is still saturated over the curve *unless* it has been heated and then cooled slowly, and is still over the line (in this case, it is supersaturated). What is correct? Thank you for your video-super helpful in my understanding.
Your professor is correct. Supersaturation is only a special case of being above the line. Normally it would just be saturated, in equilibrium with itself if above the line.
Another great video. I love your channel! Your explanations and illustrations are perfect.
Thanks so much for making this. It went with almost exactly with my teacher's lesson and explained it all far better.
This is great. Covers everything. chemistry in a bottle, all in one, luv your channel.
the best teacher ever
😊
best explanation
really nice and easy explanation
Thanks!
Great video sir., It takes a lot of work to make videos with the PowerPoint presentation I suppose.

@@CrashChemistryAcademy thanks so much!
you're welcome!
Wonderful video sir! Helpful yet again.
P.S. I watched this video straight after your VB Theory video; and your voice just absolutely changed. 😅☹️
Yah, my voice is not very consistent. Well as long as you can understand what I'm saying, I'm happy.
When is the next video coming out?
I'm aiming for about 2-3 weeks.

Thanks for the reminder, I will have to get those put in.
