To prove that a specific solute can diffuse through a semipermeable membrane, you could set up an experiment where the solute is placed on one side of the membrane, and a solution without the solute is on the other side. Over time, you would measure the concentration of the solute on both sides of the membrane. If the concentration increases on the side without the solute, it indicates that diffusion has occurred. To disprove diffusion, you would find that the concentration remains unchanged on the opposing side, suggesting that the solute cannot pass through the membrane.
Water molecules freely diffuse across a semipermeable membrane.
Ions diffuse across the membrane through specific ion channels that are embedded in the cell membrane. These ion channels are selective, allowing only specific ions to pass through based on size, charge, and other factors. The movement of ions through these channels is facilitated by a combination of concentration gradients and electrochemical forces.
Lipid-soluble substances, such as oxygen, carbon dioxide, and small non-polar molecules, easily diffuse across the cell membrane. These substances can pass through the lipid bilayer of the membrane without the need for specific transport proteins.
Sugar molecules do not diffuse through a plant cell membrane because they are too large and polar to pass through the hydrophobic interior of the lipid bilayer. Instead, sugar molecules are transported across the membrane by specific transport proteins, such as sugar transporters, that facilitate their movement into the cell.

A semipermeable membrane
No, iodine potassium iodide mixed with starch cannot diffuse through a semipermeable membrane because the starch molecules are too large to pass through the pores of the membrane. Only smaller molecules like iodine will be able to pass through.
An impermeable solute is a substance that cannot pass through a semipermeable membrane, such as a cell membrane. This means that the solute is unable to diffuse or move across the membrane and remains on one side of the membrane.
Diffusion is simply the movement of one molecule from an area of high concentration to low concentration. It is semi related to the plasma membrane because plasma membrane does allow diffusion, to an extent. Plasma membrane is semipermeable and only allows certain things to diffuse in or diffuse out.

Osmosis
starch doesnt diffuse through the dialysis membrane.
Yes, ions can diffuse through a membrane.
When water diffuses through a semipermeable membrane, such as a cell, it is called osmosis. In osmosis the concentration of water will differ on one side of the membrane from that of the other side. Water molecules will tend to diffuse from the high concentration side to the lower.
No, oxygen cannot directly diffuse across a cell membrane. Instead, it crosses the cell membrane with the help of specific transport proteins, such as aquaporins and oxygen channels. These proteins facilitate the movement of oxygen from areas of high concentration to low concentration.
