When you view as ii aqueous consequences piddle tends to move from where there is a elevated amount of operose peeing to where there is a high amount of solute. This toilet also be said as water decease from a hypotonic (high water concentration) to a hypertonic (low water concentration) solution. This is an example of a substance moving down its concentration gradient. In regularise to set up an taste where one and only(a) could enter out the molars of these unknown solutions you would select a four beakers, a graduated cylinder, 4 dialysis provides labelled 1,2,3,4, and twine. to a fault the pipe has to be permeable to water yet non to any types of sugar. first gear tie one end of each of the dialysis tubes with a string near the bottom rattling tightly in order to prevent leaking.
Then shopping mall 250 ml of distilled water in the beakers. It is essential that distilled water is use because it is lay off of all impurities. Also it is important that the water is all the said(prenominal) temperature so that variables potful be purged. Then correspond 10 ml of solution A, B, C, and D to each one of the dialysis tubes 1, 2, 3 and 4 respectively. contact the other end of the tube with a string but leave room for possible...
