It's interesting, isn't it? Sucrose stays intact - no chemical change in the formula. Just each sugar molecule surrounded by water. Whereas NaCl disassociates into two separate ions: Na+ (surrounded by water molecules) and Cl- (surrounded by water). We call the kinds of compounds that break apart into ions "electrolytes." This is because when you dissolve an electrolyte it can conduct electricity! So sugar water doesn't conduct electricity, but salt water does.
@@Socratica Okay, but I think we can separate Salt from water just by boiling it by which water molecules will be evaporated where salt will remain in the container! I think it's the physical method to reverse a reaction which indicate physical reaction. Isn't it so?
It is getting complicated, right? You boiled the *water*, and the water is unchanged. The water experienced a physical change, and at no point changed its chemical composition. But the NaCl is undergoing decomposition and then composition. It literally comes apart into separate ions, and then after you drive the water off completely, now it can recombine to form NaCl again. Composition and decomposition are genuine CHEMICAL reactions - meaning, the chemical formula has changed. Na+ and Cl- separate ions are quite different chemical species than the NaCl compound. Thanks for your interesting questions!
It's all physics in the end, or to quote the famous physicist Ernest Rutherford: Physicists are real scientists, chemists are more like stamp collectors... ;-) When you get down to what actually happens in a chemical reaction it is a series of physical reactions on the atomical and subatomical level. Using the chemists way to describe what happens is a much more convenient way than using the more detailed physical calculations that in most cases gives too much unnecessary details. Looking at this in that way gives that chemistry is a branch (or subset if you want) of physics. Mathematics are just the tool we use to describe the world and allows us to do precise predictions of what is going to happen in a given situation.

We're a very small team here at Socratica! We literally do it all - writing, filming, editing...and each video we make takes many, many hours. We're hoping to get some help, but that is easier said than done. It would be a huge help if you share our videos on social media. We also have a Patreon (which will allow us to raise funds to hire help): www.patreon.com/socratica Thanks so much for watching!! 💜🦉

This is half right: Dehydration can also be understood to mean the removal of hydrogen from a compound such that we get the dehydrates.

The best channel on youtube has come to life after a long silence. Hope to see more videos.
Happy to see another sign of life from you. Don't feel pressured to do more. You are amazing as you are with your content.
This is amazing! You got me at the final one. I genuinely thought that dissolving salt in water is a physical change.
As they said, solutions are very tricky. What about a carbonated drink going flat? Physical or chemical?
this will help me with my test so much thank you
Good luck!! We're rooting for you!! 💜🦉
Nice to see you posting again.
Thank you!
This was a very great video on simple but not intuitive processes. It should have many more views.
How is dissolving sugar in liquid is a physical reaction? when dissolving salt in water isn't.

@@Socratica hmm I agree with your point now! Thanks for the illustration!
You're awesome - thanks for puzzling this through with us! 💜🦉
This was a fun video to watch
Thus helped me a lot in my science test
Great stuff, and lovely voice
thus definitely will help me with my work!
Good to hear from you again, K!
shut up
@@Ra1phael_ just so you know, you’re not supposed to use UA-cam without parental supervision when under the age of 13.
Thanks!
It's all math in the end.....
Ya, without the help of maths u cant create r understand the things around u and in the univers

Im studying fisics and chemistry
Your examples were great and made it easier to understand the material.
Good video
great video
We're so glad you're watching! 💜🦉
I think I am first view and comment.
Why don't you publish more?

First like is mine❤️... I'm a chemistry student💕
this comment shows I watched the video (don't ask school reasons)
We're glad you're here. 💜🦉
I watched the video for school
Thank you for watching!
