Why does glucose diffuse through dialysis tubing into distilled water?

Glucose diffuses through dialysis tubing into distilled water because of a process called osmosis. Osmosis is the movement of water molecules from an area of high water concentration to an area of low water concentration through a semipermeable membrane. Dialysis tubing is a semipermeable membrane, which means that it allows some molecules to pass through while blocking others. Water molecules can easily pass through dialysis tubing, while glucose molecules cannot.

When dialysis tubing is placed in distilled water, the water concentration inside the tubing is higher than the water concentration outside the tubing. This creates a concentration gradient, which causes water molecules to move from inside the tubing to outside the tubing. As water molecules move out of the tubing, they carry glucose molecules with them. This is why glucose diffuses through dialysis tubing into distilled water.

The rate of diffusion of glucose through dialysis tubing depends on several factors, including the temperature, the concentration of glucose, and the surface area of the tubing. The higher the temperature, the faster the rate of diffusion. The higher the concentration of glucose, the slower the rate of diffusion. The larger the surface area of the tubing, the faster the rate of diffusion.
