I believe the answer is when it is uncharged.
Diffusion across a cell membrane occurs when concentrations of a substance are higher either inside or outside the cell.
Osmosis is the diffusion of water across a selectively permeable membrane (see "Diffusion" above). It occurs when a solute (example: salt, sugar, protein, etc.) cannot pass through a membrane but the water can pass through. In solutions where the solute concentration is high, the concentration of water molecules is low because some of the water molecules are attached to the solute particles and thus do not contribute to diffusion. In solutions where the solute concentration is low, the concentration of unbound water molecules is high. Water moves from areas where the concentration of unbound water molecules is high (low solute concentration) to areas where the concentration of unbound water molecules is low (high solute concentration). In general, water moves toward the area with a higher solute concentration because it has a lower water concentration
The movement of solute from a region of high concentration to one of lower concentration is known as diffusion. This process occurs spontaneously as solute particles move randomly and spread out to achieve a uniform distribution in the available space. Diffusion is driven by the concentration gradient, with solute molecules moving down the gradient until equilibrium is reached.
The concentration on the solute goes from an area of high concentration to an area of low concentration
When osmosis occurs in a cell, water molecules will move across the cell membrane from an area of lower solute concentration to an area of higher solute concentration. This movement aims to equalize solute concentrations on both sides of the membrane. As a result, the cell may swell if it takes in water or shrink if it loses water, depending on the surrounding solution's tonicity.
Higher solute concentration outside the cell than that inside causes net loss of water and plasmolysis occurs. This is due to the diffusion of water to areas of higher solute concentration.
The diffusion of water through the cell membrane is called osmosis. Osmosis occurs when water molecules move across a semi-permeable membrane from an area of lower solute concentration to an area of higher solute concentration in order to equalize the concentration on both sides of the membrane.
Diffusion occurs on the cell membrane.
Solute concentration affects diffusion and osmosis by creating a concentration gradient. Higher solute concentration outside the cell will cause water to move out of the cell, leading to a decrease in cell volume. Lower solute concentration outside the cell will cause water to move into the cell, increasing its volume.
The shrinkage of cytoplasm within a cell from diffusion is known as crenation. This occurs when water moves out of the cell due to a higher solute concentration outside the cell, leading to the cell shrinking and potentially losing its functionality.

Osmosis is the diffusion of water across the cell membrance
Diffusion across a cell membrane occurs when concentrations of a substance are higher either inside or outside the cell.
The diffusion of one solute can impact the diffusion of a second solute by affecting the concentration gradient and the overall rate of diffusion in a solution. If one solute is already present and diffusing in a solution, it can change the environment and potentially hinder or facilitate the diffusion of a second solute depending on factors such as size, charge, and interaction with the solvent molecules.
Passive diffusion occurs when you have unequal concentrations of solutes on either side of a permeable membrane, therefore facilitated diffusion shouldn't require a difference in solute concentration to drive it.
Water will leave the cell by facilitated diffusion and the cell will shrink and die.
