006 Donnan Equilibrium and Driving Force

67 082 views | 22 Jul. 2010

http://www.interactive-biology.com - In this Video, I talk about Donnan Equilibrium and how it results in the Driving force.

Jay Whyte

Whooo hoo! I liked this, thank you. Simple and straightforward :)

Interactive Biology

@rohanaurora Thanks a bunch. Glad you are enjoying the videos. Stay subscribed for more :)

The Equality

That's really helps ! Thank you so much !! ?

Interactive Biology

@mazas1991 I will be working on more episodes pretty soon, but will be stepping back and starting with basic stuff. To answer your question, the Nernst equation is the formula used to calculate the Equilibrium potential for an individual ion (e.g. sodium). Donnan Equilibrium is similar to the Equilibrium potential. Goldman's equation takes all of the ions into consideration and allows you to calculate the membrane potential of the neuron. Hope that helps! Leslie

@mazas1991 The best way to contact me is to use the link in the description of the video. It goes to my Interactive Biology website. There's also a link to my facebook page on that site. All the best!

ediniz101

isnt sodium moving into the cell because of concentration gradient? and its being stopped by its charge potential?

Tapahtumahorisontti

Correct me if I'm wrong but shouldn't Donnan equilibrium require at least two permeable ions and one non-permeable anion on either side?

Bad video ...some mistakes

Interactive Biology

@Praw48 LOL, terrible puns are the best puns ;)

Diversity!

Praw48

TERRIBLE puns XD but a really helpful video. Thank you :)

Marios TsP

@InteractiveBiology i posted in ur page on facebook.this is me.

Interactive Biology

@aboylikeyou88 You are very much welcome!

Interactive Biology

@mazas1991 Like I said, send me a message from my website. Go to the site and click on the contact link. You can send any message from there

Marios TsP

@InteractiveBiology yeah its better this way.could you send me a message so i can reply because i dont know how to do it plz :S

Interactive Biology

@selenaddict The statement I think I made was that the Membrane potential is at the Equilibrium potential for Sodium. Not 100% sure what you are asking though.

Interactive Biology

@ediniz101 Yes, that can happen depending on the conditions.

Marios TsP

And i was wondering.i am confused on smthing.What is the exact difference between Nerst equation Goldmans equation and Donnan equilibrium?because i dont understand clearly what each one talks about.thanx in advance.

Majda El Hassani

Please where is the other vid to understand what happens to NA??

Athul Kp

Woww thanks that was simple enough.

Musa Ibrahim

....

Marios TsP

@InteractiveBiology thanx very much...yeap it did but i read so many stuff about it that i got confused a bit..if u can, leave an msn or fb or something so i can ask u online some questions that still confuse me..because i have an exam in 1 week so i would appreciate sooooooo much...so if u have time and will hit me up with a message or answer to this comment.thank you very very much in advance.

Interactive Biology

@Tapahtumahorisontti Not sure about that one.

Marios TsP

nice work man.well done.it was well-organized.where can i fing the other episodes?

Marios TsP

@InteractiveBiology i did it.is there anyway to talk via chat ? thanks

Interactive Biology

@mazas1991 Yeah, depending on my time availability. Send me a message and we can go from there. I don't post that info publicly on youtube for the fear of spam :)

Majda El Hassani

The way you explain is great ! I adore biology because of your vids

Types of Colloids and Their Properties

Earlier we learned that as

Earlier we learned that as far as mixtures go, we can have homogeneous solutions, or totally heterogeneous mixtures, where components don't mix. But there are actually intermediary mixtures, where substances mix to some limited degree. Let's learn about colloids as well as suspensions!

your hair is short!

Thanks for this helpful video. Needed this extra explanation for my Chemistry 2 course!!

Ashly Binas

This is what students want. This is better?❤

amit sharma

Nice Explanation

Navneeth Menon

very informative thanks man

Shane the Colloidal Silver man

My favourite is colloidal silver as it’s antiviral, antibacterial and anti fungus as well. It can reverse many health issues I’ve used it to cure bronchitis by nebulizing. I’ve also cured eye infections, eat infections, colds and flus. Silver sprays and gels for sunburns and bug bites. The best brand to buy is sovereign silver as it’s the most pure, 99.999% pure silver and pharmaceutical grade water and the particle size is the smallest at 0.8 nanometers. The 19 years of this brand being in existence not one case of Argyria because it’s so pure. Also say goodbye to superbugs because these bugs eat antibiotics for lunch but colloidal silver eats superbugs for dinner they can’t grow a resistance to silver at all. God bless hope this helps

John Adams

I love colloids. ever since 12th grade physcis class where we learned about them, I have ever since (on foggy days) say, "it looks like a colloid today" lol

Idek Tega

I don’t understand why some people actually disliked this video??‍♀️

Vijaya Raj

You are a excellent professor give fantastic explanation

Bobby Poly

Very clear explanation, you are indeed a very good teacher, thank you!!

Sultan mahmud

Dave will you make an elaborate video about "endothermic" and "exothermic" reaction. (Graph discussion and reaction would be awesome)

Jose Fernando Duran

Great video! it would be perfect if you could illustrate ionic liquids! pls!

mohammad ar-razzi hasim

salam mga kakasi?

You are a great teacher, Professor Dave. Thanks for the explanation!

i kept lokking for science for school cuz im confused

Cari

Beautiful explanation

Speed Tamizhan

I'm a tamil student ...I understood well....TQ so much...

dr sadid

Love u bro

Deanna Lemke

Fabulous

kira

i was literally about to cry i couldnt understand colloids for some reason and this video helped me thank you :)

Somaiah Jakka

Krystal Anderson

Vaccine description terms too.... biggest problem with Merck vaccines was this principle of not restirring the sludge before separating for individual doses .... don’t think for a second that Merck didn’t know they needed to remix, almost constantly, or just throw in the towel and leave people alone?

NotMarga

Thank you so much for posting and explaning!!
I'm having an exam and one of the pointers is "Types of colloids"
but our teacher still hasn't explained it so I got on my computer and searched it
and then this popped up! thank you!

Sonu Sangwan

He is an amazing teacher. We need more teachers like him in India

what is a continuous phase?where can you find it in aq phase and oil phase?

GamingLlama

Hey Dave. I know you are a scientist and all and focus more on the physical world but I would like to see maybe something on computer science maybe. Either way you are a great teacher and even if you don’t do anything in computing keep doing what you’re doing because you’re great at it :)
