The diagram below represents a laboratory experiment involving sucrose and water
molecules in a cellophane bag which functions in the same way as dialysis tubing. Which
statement correctly explains the rise of liquid in the tube at the end of the experiment?
Glass tube
DOVO
Rubber stoppor
GO
Rubbor band
Key
- Sucrose moleculo
- Water molecule
Colophano bag
At boginning of
experiment
At end of
experiment
The concentration of sucrose molecules increased as water molecules entered the bag. This
concentration increase pushed the liquid up the tube.
Water entered the bag dues to the lower concentration of water inside. The extra water pushed the
liquid up the tube as the bag filled.
Sucrose indicator entered the bag and reacted with the sucrose molecules. The reaction made the
bag increase in size and pushed the liquid up the tube.
Sucrose molecules moved out of the bag and up the tube while water moved out, causing the rise of
liquid in the tube
