if you had a dialysis bag and you put it in .4-m sucrose solution, how would that differ from distilled water?

Question

I'm in AP Bio and I really cannot figure this out. The dialysis bag contained a solution of .25% eosin, 1% starch and 1% sodium chloride.

Answer 1

It is about the osmosis.
Water moves from higher concentration to lower (I mean pure water concentration) Therefore if you put your dialysis bag in distilled water it will swell.
Now I'm assuming by ".4-m sucrose" you mean ",4 mole sucrose". Before you can figure out what will happen if you put your bag in 0.4 mole sucrose solution you have to figure out how many moles of particles (eosin, starch and sodium all together) are in the bag. then you can say which way the water molecules will move and what will happen to the bag: Swells or shrinks.

I think this is what you are asking for, right?

Answer 3

Hmm I'm guessing here,. Dialysis bag act like a kidney which filter and removed waste. Sucrose could do one, either bring more water back to the body or drain more water out of the body or neither. I like to know too.

Answer 4

i did no longer know that Jon the scientist had considered one of those radical look, lol., There are some caught up, uptight bitches on perfect right here. particularly of taking area in and giggling with regard to the photographs that have been humorous, some take their time to objective to diss Kendrick to 3 volume. relax human beings, ming ya. decrease decrease back i'm talking with regard to the uptight answereres and not something of you, who've a great experience of humor and laughed with regard to the photographs. So this would not prepare to you, yet only the few uptight, caught up ones.

Answer 5

I'm not sure I'm following what your question really is. But I CAN answer it if you explain it to me. I teach science. Glad to help you out. Messenger me on yahoo messenger. I'm
