Osmosis Experiment

[FuzzyFilmltd]

If the top part (up in the air) had a membrane of some kind that would allow the water (not the solute) out, and the water dripped back down into the container, the process would start over again. It would be a perpetual motion system, a self-propelled fountain.

I either just said something stupid or solved world energy problems.

@FuzzyFilmltd

That's fine Fuzzy. Go on and solve the world's troubles but remember I get a piece of the action.

[FuzzyFilmltd]

@SaltySky Darn it, somebody who was born before me already has companies planning osmotic powerplants.

Good for energy crisis, bad for me.

[IsRens]

Just wondering who composed the piano piece? The name of the instrumental if you wouldn't mind.

[SaltySky]

@IsRens Thanks for asking but I actually don't know. It was a tune I picked from a list that YouTube provides. I don't remember and can't find it again.

[josephdupont]

what is the membrane?

[valllhalla]

Very nice! now if you have a fresh water river, that flows out in to the ocean. Then you can make a power station with exploiting this technology. Just think

[Qhoove]

thats more of capillary action and adhesion/cohesion?

[lovemenotyou18]

ahhh.........gve us some procedure pllz........form ur egg osmosis..

[clyde0south0park]

this is cool :)

[loonmaniac]

Water molecules will move across the bloomin' membrane from the fresh water side ter the chuffin' salt water side, attemptin' ter balance the concentration of salt between the two sides. This movement of water across the bloomin' membrane will occur up ter point where the pressure differential of the bloomin' salty side over the fresh side reaches the bloody osmotic pressure, wich can be quite 'igh - several 'undred atmospheres.

Thx for taking this video!

[thehumanofthisworld]

which kind of membrane you use,

please

please

please

please, i need answer.

Where to buy this membrane?????

I will be very thankful to you, please.

[razvan616]

what kind of membrane did you use?

[SaltySky]

As I recall it was lab grade dialysis tubing, made of cellulose. Had to cut the tubing, wet it and open it up. It was secured to the wide end of the thistle tube with a rubberband, which you can see in the bottom of the beaker.

I remember doing this exact experiment in high school biology back around 1965. But there was no video camera -- we had to sit and watch it. That was the hard part.

[kl794613]

is this experiment focuse on water potential or concentrated difference???

[PS3523]

what type of starch?

[SaltySky]

Actually, it was a sugar solution. Regular table sugar.

OWNED

[RosutoRyu]

interesting but no comments during the video making it very ineducative, it only shows...

[RanmaAnime]

The experiment is aimed to demonstrate the process of osmosis. Osmosis is the diffusion of water from an area of higher water concentration to an area of lower water concentration across a semi-permeable membrane.

[RanmaAnime]

The liquid in the beaker is iodine solution and the liquid in the dialysis tubing is starch solution. The iodine solution has high water concentration, therefore it tends to move into an area of lower water concentration(starch solution). When iodine comes into contact with starch, its colour changes from clear to blue/brown.

[RanmaAnime]

In this experiment they used thistle tube and sugar solution, same concept.

[St8Solja]

how does this work?

[marijazza]

Osmotic pressures eh

[soccerandcarfan]

Dam, didn't spill!lol

[HerrStanuel]

give me fish

[narcher91]

very good
