Supersaturated Solutions - Working with Sodium Acetate

[@JezzaBazza]

Thank you so much you saved my life! Without you I would have never passed my chemistry test. This video was SUPER helpful.

[@Bigbuddyandblue]

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

[@aishwaryas4696]

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

[@JeremyKrug]

I’m so glad you enjoyed it, Aishwarya! I’ll be making more soon.

[@zalzalahbuttsaab]

Thanks for making chemistry interesting.

[@rittenbrake1613]

your voice is very soothing and easy to absorb ! Thank you !

[@rohandsouza3941]

This video was so helpful for understanding the concept of supersaturated solution thanks so much sirr

[@JeremyKrug]

Glad it was helpful. All the best on your studies in chemistry!

[@ManpreetSingh-cb8sj]

It helps a lot to those who can't access to such things

[@--PREMIUM--]

Thanks for an excellent demonstration !

[@JeremyKrug]

You're welcome. It was fun to set this up!

[@gabriellamusto3084]

Ms. Musto's 4th period chem class loves this!

[@JeremyKrug]

I'm so happy they like it! Tell them hello for me!

[@error9900]

I hadn't seen the pouring demo before. Nice!

[@JeremyKrug]

Glad you enjoyed it

[@ponbapanda2935]

this is amazing! keep doing this!

[@MuslimahForLife27]

My jaw dropped. That was so cool!

[@JeremyKrug]

Glad you liked. Thanks for watching!

[@ManpreetSingh-cb8sj]

Education should be this much advanced

[@michellewilliams-wong6834]

Thank you this was a great demonstration.

[@JeremyKrug]

So glad you enjoyed it!

Is this a chemical reaction? A phase change? Or separating a mixture? Please advise.

[@JeremyKrug]

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.

[@redrikh_putiata]

how good is that ambient music for such demonstration

[@archiesaludes1987]

Thanks this useful video. For small group activity, what is possible measure proportion of water and sodium acetate?

[@Gangofmumbai]

Wow your video is too much fucking good ❤️👍🏻

[@dhrumahyavanshi6642]

❤

[@dhrumahyavanshi6642]

Yes dude😮

[@saradagorai5076]

Wow!! It was really amazing..

[@yaseensultana9080]

Appreciating!

[@aadarshrajan6363]

Are these two different solutions of sodium acetate for the two different demonstrations or is it the same exact one?

[@JeremyKrug]

I actually used the exact same solution for both parts of the video. Great question!

[@mattmarkarian8820]

That was sick as af.

[@VIDYAAGURUKUL]

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 Dr. DEBAJIIT Chakrbarty

[@LegendsDiary704]

Salaam to you because U R a teacher.

[@JeremyKrug]

Hello Dr. Debajiit Chakrbarty, you are welcome to use my video for instruction. If you would credit my channel, that would be great!

[@VIDYAAGURUKUL]

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

[@dhaarani9912]

Great..thanks for this experiment

[@venkataramanikrishnamoorth8969]

Epic dude Jeremy

[@buddyguy4723]

that butt chin is putting in some work. good video

[@jasonpatterson9821]

Krug life!

[@mdmubashiralimnoor2431]

will it only dissolve with distilled water? cuz i've seen few videos which tell that distilled water will only work.

[@JeremyKrug]

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.

[@hadiatubangura9316]

Great video sir

[@sandycampbell1937]

Thanks Jeremy

[@nasimelee]

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.

[@JeremyKrug]

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!

[@meiyaoli2258]

Love this!

[@vertedheart3184]

What about the PPE; where are the gloves?

[@JeremyKrug]

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!

[@yasminmohamedelsayed2225]

Keep going ❤️

[@phan3833]

Will it work (crystallize) if I use sodium acetate trihydrate instead?

[@JeremyKrug]

Yes, it should work. Great question!

[@LegendsDiary704]

Very helpful. Allah may bless you

[@ManpreetSingh-cb8sj]

Amazing

[@DesaiVandana1]

Sodium acetate can we take salt ?

[@JeremyKrug]

It needs to be sodium acetate, regular table salt (NaCl) won't work for this.

[@mousmighosh1333]

It was amazing

i put the water with sodium acetate in the microwave

[@JeremyKrug]

That works too. I'm all in favor of shortcuts!
