[Osmosis Experiment]
[Refer to above picture]
If we take more concentrated sugar solution in the thistle funnel and very dilute concentrated sugar solution with water in the beaker...will a small amount of sugar solution enter the beaker??
Because in the book it is given the water will enter the thistle funnel but it is not given if sugar will enter the beaker or not??
Answers
When we take concentrated sugar solution in thistle funnel and dilute solution in the beaker obviously water molecules show movement from dilute solution in the beaker to concentrated solution in the thistle funnel because concentration of solvent i.e.water is less inside and more outside. The reason being osmosis which is the movement of solvent molecules from region of higher concentration to a region of lower concentration through a membrane (here cellophane membrane) .
Solute particles don't show any movement because the semipermeable cellophane membrane allows the movement of small solvent molecules through it but restricts the movement of large solute molecules so that's why in the given experiment sugar won't enter or leave the beaker but water from the sugar solution will move from beaker to funnel due to difference in concentration i.e.concentration gradiant.
