- Super absorbent polymers retain large amounts of liquids. What can they be used for? Mostly for diapers, but they can also be used in agriculture to retain water, and in crafts and toys. Sodium polyacrylate is a preferred material and the degree of crosslinking will dictate the absorbent capacity, lower crosslinking will absorb more water.
Enjoy the superabsorbent demonstration! Think of other applications!!!

The most sympathetic Karen I know! Just so interesting!
😊
Cool stuff! ❤
What are the long-term environmental effects of polymers? Will this naturally biodegrade once the water evaporates, or does it become a plastic forever sludge?
I dont know what is that 8 teaspoon
Hi can u tell me hcl acid thickner, real chemicals name
Mam, can you please say how can we make sap from peels of oranges??
Is there a way to retain the SAP in powder form again? Maybe by heating it?
Si agregas sal puedes separar el agua del polimero. Igual calentandolo o solo dejando al sol puedes evaporar el agua. Si le echas la sal ya no vuelve a absorber
Good day to you, I want to convert the "gallon" mentioned in the video to liters. May I know how much is that 1 gallon of water in the video when converted to liters?
Hello, so a gallon is about 4 liters, exactly 3.79 liters but 4 will do it
could you pls instruct me to make a polymer at home
You mean from scratch?
Hi Karen,
Is there some way of adding chemical to the water in order to make the SAP harder?
That's a good question! Why would you be interested in making the SAP harder?
@@karenslab8484 We use them in a sport called Gel Ball. Unfortunately due to the soft nature of the gels, they are inaccurate at the best of times. To make them harder and/or heavier would be very helpful. Would you have any ideas?
@@karenslab8484 Can you assist with this query please?
@Robert Mclellan Do you have a way to solve the problem of gel hardening?
But some brends don't work well
I wonder why……
Totally agree, check the video of the snow, if the ratio changes it behaves quite differently
Can we use this as snow??
+deepu chmr hello, not really, even though it is the same material as the one shown in the snow video, better said same polymer, it has different degree of crosslinking, watch the snow video. Therefore this one absorbs quite a bit of water without forming discrete particles like the snow, this one basically gels
Is there anyway this can be reversed back to water?
Yes, add salt and this will break up absorption releasing the water 💦
@@karenslab8484 thank you madam 🙂 I was looking for this answer.
8tea spoon SAP + 1gallon water = how much gallon ?????????? it could be less than 1gallon? or over 1gallon?
Hi! A gallon is 3.8 liters, yes it can be less than that or a bit more, if you add too much is just very watery until quite watery.
@@karenslab8484 i mean you only add exactly 3.8 liters water and only exactly 8 tea spoons of SAP. Then how much gallon is the result?
Could you please tell me the exact name of polymer name??? Because I want make diapers
Hi! The polymer used to absorb liquids is sodium polyacrylate
How to make super absorbent powder?
Hello! Well is a polymer synthesis process. Which involves polymerization of a blend of acrylic acid with sodium hydroxide with an initiator. This chemical process results in the polymer referred sodium polyacrylate
@@karenslab8484 Hi! its me again, Can I ask more about more on making super absorbent polymers?….I would love to connect with you through email or other convenient platforms. Btw, I am an agronomy student😅
What happned if you eat it?
Oh no don’t do it, it is quite irritant, when working with it it can irritate your hands as well, same with your eyes and mucous membranes
@@karenslab8484 Okay, Yesterday I was going to get ice for my drink, So I took and poured the ice in my drink after a while there was gel in my whole drink, So then I understood that I had accidentally taken freezer clamps!
Oops 😬
Lol 8 teaspoons = 0 teaspoons
Hi Miss Karen, I am a student at VietNam national university, and I studying chemical engineering technology. Now I am studying about SAP. I want to ask you some question about it. Can you take me your email ? I hope the response from you. Thank you very much.
Sure, karen.lozano.lab@gmail.com
@@karenslab8484 May I also ask you some questions about SAP? I am a senior highschool student from the Philippines and I am planning to make a research paper about SAP using organic materials. Thank you for the consideration.
Diapers ;-;
Aight
If you add anything to either cup, it is no longer empty...so you lied, you DIDN'T have 2 empty cups🧐🙄
OUT OF HERE AT 1:59😡
Hello! Is a super absorbent polymer, check at 0.46, adding the polymer, then check at 1.00 adding water and then at 1:15 transferring the water to the cup that has the powder but it all gets absorbed and forms a gel which is later explained
