- In this video, Mr. Krug shows how to make a supersaturated solution of sodium acetate and what these interesting solutions can do.
Remember, always work safely, using safety goggles and working under the supervision of your teacher or another responsible adult.

Thank you so much you saved my life! Without you I would have never passed my chemistry test. This video was SUPER helpful.
I have one of those therapeutic chemical heat packs, and when it’s in liquid state, you pinch a spot on the pack, which starts the reaction. You can watch the crystals forming, the pack heats up to use as a heat pad. After you use it, you then boil the pack in a pot of water until the crystals re-dissolve. After it cools down, it’s ready to use again. I’ve been using it for over 10 years, and it still works!
I just found out about it at mall of america. The wonder pax. Works amazing
Thanks for making chemistry interesting.
Thank you for making such on insightful video! I wish Chemistry is taught this way in all schools and colleges instead of boring theory class!
Thank you again
I’m so glad you enjoyed it, Aishwarya! I’ll be making more soon.
I hadn't seen the pouring demo before. Nice!
Glad you enjoyed it
your voice is very soothing and easy to absorb ! Thank you !
Thanks for an excellent demonstration !
You're welcome. It was fun to set this up!
This video was so helpful for understanding the concept of supersaturated solution thanks so much sirr
Glad it was helpful. All the best on your studies in chemistry!
It helps a lot to those who can't access to such things
Ms. Musto's 4th period chem class loves this!
I'm so happy they like it! Tell them hello for me!
My jaw dropped. That was so cool!
Glad you liked. Thanks for watching!
Education should be this much advanced
Thank you this was a great demonstration.
So glad you enjoyed it!
how good is that ambient music for such demonstration
Thanks Jeremy
Thanks this useful video.
For small group activity, what is possible measure proportion of water and sodium acetate?
Is this a chemical reaction? A phase change? Or separating a mixture? Please advise.
Hi Sean,
(1) This does have characteristics of a chemical reaction. Although crystallization of a solid from a solution is a physical change, we are also forming an ionic bond (chemical bond) between the ions of sodium and acetate. So we can make a case that this is a chemical reaction, while we can also make a case that it is a physical change. Neither would be incorrect, chemically speaking.
(2) Not truly a phase change. We are going from an aqueous mixture (specifically, an ionic solid dissolved in water) to a solid with a little water present.
(3) Definitely separating a mixture. The aqueous mixture contains sodium acetate and water, while the 'crystallized' version contains solid sodium acetate with a little liquid water.
this is amazing! keep doing this!
Appreciating!
Wow your video is too much fucking good ❤️👍🏻
❤
Yes dude😮
Respected sir
I want to show your this video to my students in my you tube channel without any tampering or changes.
If you ready or give me a permission than I will show this unique video in my animated video or during lecture.
Thank you

Salaam to you because U R a teacher.
Hello Dr. Debajiit Chakrbarty, you are welcome to use my video for instruction. If you would credit my channel, that would be great!
Thank you so much respected sir for your love and support
I am add your channel name and credit in my description box.
Again thank you so much sir
Great..thanks for this experiment
that butt chin is putting in some work. good video
Wow!! It was really amazing..
Are these two different solutions of sodium acetate for the two different demonstrations or is it the same exact one?
I actually used the exact same solution for both parts of the video. Great question!
Very helpful. Allah may bless you
That was sick as af.
Krug life!
Amazing
Great video sir
It was amazing
will it only dissolve with distilled water? cuz i've seen few videos which tell that distilled water will only work.
You can use tap water, but due to the impurities in tap water, you might not be able to dissolve the full amount. This is why I recommend distilled water.
Hello Mr Krug, I cannot get this to work. I’ve tried multiple times. I get the sodium acetate to dissolve and set it out to cool on the kitchen counter. Our house is 76degrees. It crystallizes before it gets to room temperature. What am I doing wrong? How can we make it work. My son chose this topic for his 6th grade science experiment and I though it would be great because he could do it independently but he tried so many times and got frustrated so I tried to with the same (poor) results.
A couple of tips... Make sure you're using distilled water. Tap water has enough impurities that this likely won't work unless you use distilled water. Also, make sure that your beaker is very clean. A dirty beaker might have impurities that could dissolve into the water and keep your solution from getting to the supersaturated point. Just a couple of thoughts. Best wishes on your science project!
Epic dude Jeremy
What about the PPE; where are the gloves?
In this demo, I used safety goggles and a lab coat/apron, as I do in all my demos. Sodium acetate is not especially corrosive, so gloves are not really necessary for this demo, although if someone wanted to use them, that would be fine. In my many years of experience, using gloves when they aren't really necessary leads to (1) excess waste of polymers/plastics, and (2) more risk of slippage between your hands and the glass beaker -- esp in the case of reusable gloves -- which increases the risk of dropping the beaker and having an accident. As always, if you touch the 'seed crystal' with your fingers, wash your hands afterwards. Thanks for watching!
Will it work (crystallize) if I use sodium acetate trihydrate instead?
Yes, it should work. Great question!
thanks for the experience
Love this!
You've got the grayble lable!
Keep going ❤️

WOWZERS
😊
How does this even work!!!
This is how non-spelean speleothems formed on Martian surface.
Who else is here after reading page 11 of the Chemistry PACE 1126??? iykyk 😅
how is this even possible
👀
interesting
Jorden peterson brought me here.
Hmm. Sodium acetate 3D printer...
